The invention claimed is: 1. A communication device comprising: a board having a first surface, a second surface opposite to the first surface, and a third surface different from both the first surface and the second surface; a first magnetic sheet disposed on a side of the first surface; a first coil disposed on the first magnetic sheet; a second magnetic sheet disposed on a side of the second surface; a second coil disposed on the second magnetic sheet; and a third coil disposed on the third surface, wherein a first part of the first magnetic sheet overlaps at least a part of the third coil in plan view. 2. The communication device according to claim 1 , wherein the first coil is a wireless charging coil, the second coil is a near-field communication (NFC) coil, and the third coil is a near-field magnetic induction (NFMI) coil. 3. The communication device according to claim 2 , further comprising: a battery, wherein the board has a fourth surface opposite to the third surface, the battery is disposed on the fourth surface, and a second part of the first magnetic sheet overlaps at least a part of the battery in plan view. 4. The communication device according to claim 2 , wherein the third coil is disposed on a first notched part on the third surface. 5. The communication device according to claim 2 , further comprising: a battery, wherein the board has a fourth surface, and the battery is disposed on a second notched part on the fourth surface. 6. The communication device according to claim 2 , wherein an area of the first coil is larger than an area of the second coil in plan view, and a part of the first coil overlaps at least a part of the second coil in plan view. 7. The communication device according to claim 2 , further comprising; at least one electric component, wherein the at least one electric component is disposed between the first surface and the first magnetic sheet or between the second surface and the second magnetic sheet, and a part of the at least one electric component overlaps at least a part of the first coil in plan view. 8. The communication device according to claim 2 , wherein the first magnetic sheet and the second magnetic sheet include ferrite. 9. The communication device according to claim 2 , wherein the board is a printed circuit board. 10. The communication device according to claim 2 , wherein the first coil is disposed to face a charging unit of a charger for charging of the communication device. 11. The communication device according to claim 1 , wherein an axis of the first coil is substantially parallel to an axis of the second coil. 12. The communication device according to claim 11 , wherein each the axis of the first coil and the axis of the second coil intersects with an axis of the third coil.
