Abstract
An inductor component includes an element assembly formed of an insulator material and an inner electrode arranged in the element assembly. The insulator material contains a base material formed of an amorphous material containing B, Si, O, and K and a crystalline filler and includes a filler-poor glass portion in a region along the inner electrode. The content of the crystalline filler in the filler-poor glass portion is lower than the content of the crystalline filler in the element assembly excluding the filler-poor glass portion.

An inductor component comprising:
- an element assembly formed of an insulator material;
- and
- an inner electrode arranged in the element assembly,
- wherein
- the insulator material contains a base material formed of an amorphous material containing B, Si, O, and K and a crystalline filler and includes a filler-poor glass portion in a region along the inner electrode,
- a content of the crystalline filler in the filler-poor glass portion is lower than a content of the crystalline filler in the element assembly excluding the filler-poor glass portion,
- the content of the crystalline filler in the filler-poor glass portion is lower than the content of the crystalline filler in a center portion of the element assembly, and
- the filler-poor glass portion is in direct contact with the inner electrode around an entire circumference of the inner electrode when viewed as a cross-section along an axial direction of the inner electrode.
