Abstract

This disclosure provides a magnetic material-containing resin to be used for coating and forming cores. A magnetite-containing resin of the present invention includes a magnetite having a residual magnetic flux density of less than 15 Am 2 /kg and a coercive force of less than 12 kA/m. A coil is provided that has a structure in which by coating a winding with the magnetite-containing resin, a magnetite-containing resin layer is formed.

First claim

What is claimed is:

1. An electronic component comprising:
a magnetite-containing resin comprising:
a resin; and
a powdery magnetic material incorporated into the resin,
wherein the magnetic material at least partially includes a magnetite having a residual magnetic flux density of less than 15 Am 2 /kg and a coercive force of less than 12 kA/m;
a core composed of the magnetite-containing resin; and
a winding wound around the core or a pattern disposed on a surface of t…
