  • Publication number: 20240096551
    Abstract: A method of manufacturing an inductor component includes preparing an insulating paste that is photosensitive and that includes a filler material composed of quartz, a glass material and a resin material, and a conductive paste, forming a first insulating layer by applying the insulating paste, and exposing the first insulating layer in a state where a first portion of the first insulating layer is shielded by a mask. The method further includes removing the first portion of the first insulating layer to form a groove at a position corresponding to the first portion, applying the conductive paste in the groove to form a coil conductor layer in the groove, and applying the insulating paste on the first insulating layer and the coil conductor layer to form a second insulating layer.

  • Publication number: 20240047129
    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.
