1. 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, and
a portion of the element assembly excluding the filler-poor glass portion is arranged directly between a first portion of the filler-poor glass portion, and a closest second portion of the filler-poor glass portion.
