Abstract

In substrate-mounting type inductor having a winding having conductivity, a core on which the winding is winded, and a terminal portion arranged at an end of the winding, a recessed portion which is recessed in a direction of height of the core is formed on a substrate mounting surface of the core, and the terminal portion is arranged to be housed in the recessed portion through an insulating member.

Claims (27)

1. A substrate-mounting type inductor having:

a conductive winding;

a core on which the conductive winding is wound; and

an insulating member;

the conductive winding comprising:

a terminal portion located at an end of the conductive winding;

the core comprising:

a recessed portion which is recessed in a height direction of the core and formed on a substrate mounting surface of the core;

wherein the terminal portion is arranged to be housed in the recessed portion;

wherein the insulating member is located between the terminal portion and the recessed portion; and

wherein the insulating member does not extend away from the substrate mounting surface of the core.

2. The inductor according to claim 1 ;

wherein a part of the terminal portion and a part of the insulating member are coplanar with a surface of the core.

3. The inductor according to claim 1 ;

the core further comprising:

an E-type core comprising a middle leg which supports the conductive winding; and

a plate-like I-type core arranged to cover an open surface of the E-type core.

4. The inductor according to claim 3 ;

wherein the recessed portion is formed on a surface of the I-type core.

5. The inductor according to claim 1 ;

wherein the conductive winding further comprises a flat wire, and an end of the flat wire is used as the terminal portion.

6. The inductor according to claim 5 ;

wherein a part of the terminal portion and a part of the insulating member are coplanar with a surface of the core.

7. The inductor according to claim 5 ;

the core further comprising:

an E-type core comprising a middle leg which supports the conductive winding; and

a plate-like I-type core arranged to cover an open surface of the E-type core.
