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 protruded from a side surface of the core; and

a tabular terminal, apart of which protruded from the side surface of the core and partly connected with the protruded part of the terminal portion of the coil,

wherein 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.

2. The coil component according to claim 1,

wherein a cutout is provided in an end portion of the tabular terminal on the side to be embedded in the core, and

wherein the terminal portion of the coil is arranged such that a part thereof fits in the cutout.

3. The coil component according to claim 1, wherein a groove for accommodating the protruded and bent part of the terminal portion of the coil is provided in the side surface of the core from which the terminal portion of the coil protrudes.
