Abstract
Disclosed herein is a coil component that includes an element body having a mounting surface, a coil part embedded in the element body, and a first conductor post embedded in the element body. The first conductor post has a first end connected to the coil part and a second end exposed from the mounting surface. A surface of the element body on the mounting surface side has a recess from a surface of the first conductor post.
Claims6
A coil component comprising:
- an element body having a mounting surface;
- a coil part embedded in the element body;
- and
- a first conductor post embedded in the element body,
- wherein the first conductor post has a first end connected to the coil part and a second end exposed from the mounting surface, and
