Claim 19:
20. 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 10% or less 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.
