Abstract

An electronic component includes; a magnetic-body core having a plate-shaped portion and a core portion which extends from an upper surface of the plate-shaped portion; a winding wire which includes a wound portion wound by a rectangular wire into an Edgewise winding form and two non-wound portions extending from the wound portion to two distal ends, and the core portion is inserted through the wound portion; and a magnetic exterior body which covers at least the wound portion and the core portion. The two non-wound portions are respectively arranged along a bottom surface and at least one of the side surfaces of the plate-shaped portion. Parts of the two non-wound portions arranged along the bottom surface are electrodes.

Claims (48)

1. An electronic component comprising:

a magnetic-body core that includes:

a plate-shaped portion having an upper surface, a bottom surface, and a plurality of side surfaces, the plurality of side surfaces including first and second side surfaces, and

a core portion extending from the upper surface of the plate-shaped portion;

a winding wire that includes a wound portion wound by a rectangular wire into an Edgewise winding form and first and second non-wound portions, the first and second non-wound portions extending from the wound portion to first and second distal ends, the core portion being inserted through the wound portion; and

a magnetic exterior body that covers the wound portion, the core portion, the upper surface of the plate-shaped portion, and the plurality of side surfaces of the plate-shaped portion,

wherein the first and second non-wound portions are respectively arranged along the bottom surface and the first and second side surfaces of the plate-shaped portion,

a first part of the first non-wound portion and a second part of the second non-wound portion arranged along the bottom surface of the plate-shaped portion are electrodes,

third and fourth parts of the first non-wound portion arranged along the first and second side surfaces, respectively, are exteriorly exposed relative to the magnetic exterior body,

fifth and sixth parts of the second non-wound portion arranged along the first and second side surfaces, respectively, are exteriorly exposed relative to the magnetic exterior body,

exteriorly exposed lengths of the third, fourth, fifth, and sixth parts are the same, and

each of the first and second distal ends of the first and second non-wound portions is inwardly bent toward the wound portion, and the first and second distal ends of the first and second non-wound portions are embedded into the magnetic exterior body so that the first and second non-wound portions are fixed to the magnetic exterior body via the embedded first and second distal ends.

2. The electronic component according to claim 1 ,

wherein the plate-shaped portion and the core portion of the magnetic-body core are independent members which are combined together to form the magnetic-body core.

3. The electronic component according to claim 1 ,

wherein the first and second distal ends of the first and second non-wound portions are proximate the second side surface of the plate-shaped portion.

4. The electronic component according to claim 1 ,

wherein each of the first and second non-wound portions has a step between the wound portion and one of a plurality of side surfaces of the magnetic exterior body that is proximate the first side surface of the plate-shaped portion.

5. The electronic component according to claim 1 ,

wherein each of the first and second distal ends of the first and second non-wound portions is bent at a right angle.

6. The electronic component according to claim 3 ,

wherein each of the first and second distal ends of the first and second non-wound portions is bent at a right angle.

7. The electronic component according to claim 4 ,

wherein each of the first and second distal ends of the first and second non-wound portions is bent at a right angle.

8. The electronic component according to claim 3 ,

9. The electronic component according to claim 5 ,

10. The electronic component according to claim 6 ,

11. The electronic component according to claim 1 ,
