Abstract
Disclosed herein is a coil component that includes a magnetic element body, and a coil part embedded in the magnetic element body. The magnetic element body includes a first region covering the coil part from one side in a coil axis direction, a second region covering the coil part from other side in the coil axis direction, and a third region positioned in an inner diameter area of the coil part so as to connect the first and second regions. The height of the coil part in the coil axis direction decreases toward the inner diameter area.
Claims5
A coil component comprising:
- a magnetic element body;
- and
- a coil part embedded in the magnetic element body,
- wherein the magnetic element body includes a first region covering the coil part from one side in a coil axis direction, a second region covering the coil part from other side in the coil axis direction, and a third region positioned in an inner diameter area of the coil part so as to connect the first and second regions, and
- wherein a height of the coil part in the coil axis direction decreases toward the inner diameter area.
A method for manufacturing a coil component, the method comprising:
- forming a coil part;
- forming, on one side in a coil axis direction of the coil part and in an inner diameter area of the coil part, a first magnetic element body;
- deforming a surface on other side in the coil axis direction of the coil part such that a height in the coil axis direction of the coil part decreases toward the inner diameter area;
- and
- forming a second magnetic element body on the other side in the coil axis direction of the coil part.
