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 o 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 terminal portion of the coil including a protruding part which protrudes from a side surface of the core and bends toward a bottom surface side of the core along the side surface of the core;

a tabular terminal, a part of which protrudes from the side surface of the core, bends toward the bottom surface side of the core along the side surface of the core, and partly connects with the protruding part of the terminal portion of the coil; and

a first groove provided in the side surface of the core from which the protruding part protrudes, the first groove partly accommodating the protruding part of the terminal portion of the coil, protruding from the side surface of the core and bending toward the bottom surface side of the core,

wherein a part of the protruding part of the terminal portion of the coil, accommodated in the first groove, is arranged between the part of the tabular terminal, protruding from the side surface of the core and bending toward the bottom surface of the core, and the side surface of the core, and

wherein the part of the tabular terminal, protruding from the side surface of the core and bending toward the bottom surface side of the core, connects with the protruding part of the terminal portion of the coil at the part of the protruding part of the terminal portion of the coil accommodated in the first groove.

2. The coil component according to claim 1, further comprising a second groove provided in the side surface of the core from which the protruding part of the terminal portion of the coil and the protruding part of the tabular terminal protrude, respectively, the second groove accommodating the part of the tabular terminal protruding from the side surface of the core, and the first groove provided in the second groove.

3. The coil component according to claim 2, wherein the first groove is narrower in width than the second groove.

4. The coil component according to claim 2, wherein the first groove is provided substantially in a center of the second groove.

5. The coil component according to claim 2, wherein the second groove is provided so as to continue from the side surface of the core to the bottom surface of the core.

6. The coil component according to claim 2, wherein the side surface of the core includes an uppermost edge and a lowermost edge, the second groove extending along the side surface of the core from the uppermost edge to the lowermost edge.
