Abstract

A coil component includes a core formed by a magnetic material, a coil embedded in the core, a part of a terminal portion of the coil protruded from a side surface of the core, and a tabular terminal, a part thereof protruded from the side surface of the core and partly connected with the protruded part of the terminal portion of the coil. The protruded part of the terminal portion of the coil and the protruded part of the tabular terminal are respectively bent toward the bottom surface side of the core along the side surface of the core, and the protruded and bent part of the terminal portion of the coil is arranged between the protruded and bent part of the tabular terminal and the core.

Claims

1. A coil component comprising:

a core formed by a magnetic material;

a coil embedded in the core, a part of a terminal portion of the coil protruding outside of the core;

a tabular terminal, one end being embedded in the core, and an other end protruding outside of the core and being connected with the protruding part of the terminal portion of the coil, and

a groove formed in a side surface of the core, the groove having a plane parallel to and recessed inward from a side surface of the core, the groove extending from a position where the terminal portion of the coil and the tabular terminal protrude outside of the core toward a bottom surface of the core,

wherein the protruding part of the terminal portion of the coil and the protruding part of the tabular terminal protrude outside of the core at an upper end part of the groove,

wherein the protruding part of the terminal portion of the coil and the protruding part of the tabular terminal are, respectively, bent toward the bottom surface of the core along the plane of the groove, and

wherein apart of the side surface of the core above where the terminal portion of the coil and the tabular terminal protrude outside of the core being located on a plane of the side surface of the core which is disposed outward from the plane of the groove.

2. The coil component according to claim 1, wherein the protruding and bent part of the terminal portion of the coil is arranged between the protruding and bent part of the tabular terminal and the core.

3. The coil component according to claim 1, wherein a cutout is provided in the one end portion of the tabular terminal embedded in the core, and the terminal portion of the coil is arranged such that a part thereof fits in the cutout.

4. The coil component according to claim 1, wherein the groove comprises a first groove portion for accommodating the protruding and bent portion of the terminal portion of the coil.

5. The coil component according to claim 4, wherein the groove further comprises a second groove portion for accommodating the protruding and bent portion of the tabular terminal.

6. The coil component according to claim 5, wherein the first groove portion is provided substantially in a center of the second groove portion.

7. The coil component according to claim 5, wherein the second groove portion continues from the side surface of the core to the bottom surface of the core.
