Abstract

An electronic component which includes a first side-surface and a second side-surface facing the first side-surface, including: a magnetic-body core including a plate-shaped portion and a core portion; a winding wire which includes a wound portion wound with a rectangular wire and two non-wound portions, and of which the core portion is inserted through the wound portion; a magnetic exterior body; a first electrode member including a first side-surface exposed-portion; and a second electrode member including a second side-surface exposed-portion, wherein the first side-surface exposed-portion includes a first connecting portion which extend along the height direction of the first side-surface, the first connecting portion is connected to one of the non-wound portions, the second side-surface exposed-portion includes a second connecting portion which extends along the height direction of the second side-surface, and the second connecting portion is connected to the other of the non-wound portions.

Claims

1. An electronic component which includes a first side-surface and a second side-surface facing the first side-surface, comprising:

a magnetic-body core including a plate-shaped portion and a core portion which extends from the upper surface of the plate-shaped portion;

a winding wire which includes a wound portion wound by a rectangular wire and two non-wound portions from the wound portion up to two distal ends, and of which the core portion is inserted through the wound portion;

a magnetic exterior body which covers at least the wound portion and the core portion;

a first electrode member including a first side-surface exposed-portion which is exposed along the first side-surface; and

a second electrode member including a second side-surface exposed-portion which is exposed along the second side-surface, wherein

the first side-surface exposed-portion includes a first connecting portion which extends along the height direction of the first side-surface,

the first connecting portion is connected to one of the non-wound portions,

the second side-surface exposed-portion includes a second connecting portion which extends along the height direction of the second side-surface, and

the second connecting portion is connected to the other of the non-wound portions.

2. The electronic component according to claim 1, wherein the wound portion is wound by a rectangular wire into a Flatwise winding form.

3. The electronic component according to claim 1, wherein the non-wound portions are pullout at the angle positions of the magnetic-body core.

4. The electronic component according to claim 1, wherein the magnetic exterior body includes an admixture of a magnetic material and a resin.

5. The electronic component according to claim 1, wherein the lower end of the magnetic exterior body positions at a predetermined position in the height direction of the side surface of the magnetic-body core.

6. The electronic component according to claim 1, wherein there is a height difference between pullout positions of the non-wound portions from the magnetic exterior body.

7. The electronic component according to claim 1, wherein distal ends of the connecting portions are bent 180 degrees so as to warp the distal ends of the non-wound portions separately.

8. The electronic component according to claim 1, wherein the first or the second connecting portion extends from the center of the first or second side-surface exposed-portion.
