Abstract

An electronic device includes a chip component including a terminal electrode, a case having an accommodation recess accommodating the chip component, a conductive terminal attached to the case and connected to the terminal electrode, and a case cover disposed on an opening-edge surface of the case so as to cover the accommodation recess. The opening-edge surface has an opening-edge recess at least partly covered by the case cover. The opening-edge recess and the case cover have a space therebetween. The space is filled with a resin.

First claim

What is claimed is:

1. An electronic device comprising:
a chip component including a terminal electrode;
a case having an accommodation recess accommodating the chip component;
a conductive terminal attached to the case and connected to the terminal electrode; and
a case cover disposed on an opening-edge surface of the case so as to cover the accommodation recess;
wherein
the opening-edge surface has an opening-edge recess at least partly covered by the case cover;
the opening-edge recess and the case cover have a space therebetween; and
the space is filled with a resin.

2. The electronic device according to claim 1 , wherein the opening-edge recess extends along a periphery of the accommodation recess so as to surround the accommodation recess.

3. The electronic device according to claim 1 , wherein
the opening-edge surface comprises an inner opening-edge surface and an outer opening-edge surface located outwards from the inner opening-edge surface; and
the case cover is disposed on the inner opening-edge surface.

4. The electronic device according to claim 3 , wherein a distance between the inner opening-edge surface and a bottom of the case is shorter than a distance between the outer opening-edge surface and the bottom of the case.

5. The electronic device according to claim 3 , wherein
the conductive terminal comprises an opening-edge electrode portion disposed over the opening-edge surface; and
the opening-edge electrode portion comprises an inner anchoring portion disposed between the inner opening-edge surface and the case cover, and an outer exposed portion disposed over the outer opening-edge surface and exposed outside.

6. The electronic device according to claim 1 , wherein
the case comprises a wall surrounding the accommodation recess;
the wall comprises an outer wall portion located outwards from the opening-edge recess; and
the case cover is accommodated in a case cover accommodation portion surrounded by the outer wall portion.

7. The electronic device according to claim 1 , wherein
the case cover comprises a leg portion at a periphery of the case cover; and
the leg portion engages with the opening-edge recess.

8. The electronic device according to claim 7 , wherein the space is provided between the leg portion and a bottom of the opening-edge recess.

9. The electronic device according to claim 7 , wherein
the conductive terminal comprises an opening-edge electrode portion disposed over the opening-edge surface;
the opening-edge electrode portion comprises a bent portion bent towards a bottom of the opening-edge recess; and
the bent portion is disposed between the bottom of the opening-edge recess and the leg portion.

10. The electronic device according to claim 1 , wherein
the case comprises a wall surrounding the accommodation recess; and
the wall comprises an outer wall portion located outwards from the opening-edge recess, and an inner wall portion located inwards from the opening-edge recess.

11. The electronic device according to claim 1 , wherein
the opening-edge surface comprises an inner opening-edge surface and an outer opening-edge surface located outwards from the inner opening-edge surface; and
the inner opening-edge surface comprises an opening-edge sloping portion sloping down outwards.

12. The electronic device according to claim 11 , wherein
the case cover comprises a leg portion at a periphery of the case cover; and
the leg portion comprises a cover sloping portion sloping along the opening-edge sloping portion.
