wherein the reel includes a body portion extending in a stacking direction of the plurality of reels, and a flange portion formed at a position close to one end of the body portion in an extending direction of the body portion and extending toward an outer side of the body portion in a direction intersecting the extending direction; and
a plurality of pillars extending in the stacking direction of the plurality of reels and spaced apart from each other in a direction intersecting the stacking direction,
wherein a plurality of holes are formed in the body portion of the reel, a corresponding pillar being inserted into each of the plurality of holes.

2. The wiring module according to claim 1 , wherein a notch is provided in the flange portion of each real of the plurality of reels.

3. The wiring module according to claim 1 , further comprising:
a spacer disposed between the bottom plate and a reel closest to the bottom plate of the plurality of reels,
wherein an opening region communicating with the space is formed between the bottom plate and the reel closest to the bottom plate of the plurality of reels.

4. The wiring module according to claim 1 ,
wherein at least one surface of the surfaces of the module facing each other includes an optical fiber connecting portion.

5. The wiring module according to claim 4 ,
wherein both of the two surfaces of the module facing each other include the optical fiber connecting portion.

6. The wiring module according to claim 1 ,
wherein a winding diameter of the bundle of the optical fiber is larger than a diameter of the body portion of each reel of the plurality of reels.

7. The wiring module according to claim 6 ,
wherein the optical fiber is accommodated in a periphery of the body portion of the reel in a state of a bundle in which the optical fiber wound in a shape of 8 is folded back.

8. The wiring module according to claim 6 ,
wherein the optical fiber is accommodated in a periphery of the body portion of the reel in a state of a bundle in which the optical fiber is wound by reversed phase winding.

9. The wiring module according to claim 1 , further comprising:
a buffer material on which the module is placed,
wherein the buffer material is disposed in the space formed inside the plurality of reels which are stacked.

10. The wiring module according to claim 9 ,
wherein the buffer material includes a plurality of concave portions or convex portions that are fitted to a part of the body portion of each reel of the plurality of reels.

11. A frame body for a wiring module, the frame body comprising:
a bottom plate;
a plurality of reels which are sequentially stacked on an upper surface of the bottom plate, each of the plurality of reels being capable of accommodating an optical fiber; and
a buffer material on which a module is to be placed,
wherein the buffer material is disposed in a space formed inside the plurality of reels which are stacked, and
wherein the reel includes a body portion extending in a stacking direction of the plurality of reels, and a flange portion formed at a position close to one end of the body portion in an extending direction of the body portion and extending toward an outer side of the body portion in a direction intersecting the extending direction; and
a plurality of pillars extending in the stacking direction of the plurality of reels and spaced apart from each other in a direction intersecting the stacking direction,
wherein a plurality of holes are formed in the body portion of the reel, a corresponding pillar being inserted into each of the plurality of holes.

12. The frame body for a wiring module according to claim 11 ,
wherein a notch is provided in the flange portion of each reel of the plurality of reels.

13. The frame body for a wiring module according to claim 11 , further comprising:
a spacer disposed between the bottom plate and a reel closest to the bottom plate of the plurality of reels,
wherein an opening region communicating with the space is formed between the bottom plate and the reel closest to the bottom plate of the plurality of reels.

14. The frame body for a wiring module according to claim 11 ,
wherein the buffer material includes a plurality of concave portions or convex portions that are fitted to a part of the body portion of each reel of the plurality of reels.

15. A forming method for forming a wiring module including a bottom plate, a buffer material, a module having two surfaces facing each other, a plurality of optical fibers, and a plurality of reels, the forming method comprising:
a step of disposing the buffer material on an upper surface of the bottom plate and disposing the module on the buffer material;
an optical fiber bundle forming step of forming one optical fiber of the plurality of optical fibers into a bundle;
an optical fiber bundle accommodating step of accommodating the bundle of the optical fiber in one reel of the plurality of reels; and
a reel disposition step of stacking the one reel of the plurality of reels on the upper surface of the bottom plate such that the module is disposed inside the reel,
wherein the optical fiber bundle forming step, the optical fiber bundle accommodating step, and the reel disposition step are repeatedly performed until all of the plurality of reels are stacked, and
wherein in the reel disposition step performed for a second time and thereafter, the reel is disposed so as to be stacked on another reel that is already stacked on the upper surface of the bottom plate, and
wherein the reel includes a body portion extending in a stacking direction of the plurality of reels, and a flange portion formed at a position close to one end of the body portion in an extending direction of the body portion and extending toward an outer side of the body portion in a direction intersecting the extending direction; and
an extending step of extending a plurality of pillars in the stacking direction of the plurality of reels, the plurality of pillars being spaced apart from each other in a direction intersecting the stacking direction,
wherein a plurality of holes are formed in the body portion of the reel, a corresponding pillar being inserted into each of the plurality of holes.

16. The forming method for forming a wiring module according to claim 15 ,
