Abstract

A coil-type electronic component has a coil inside or on the surface of its base material wherein the base material in the coil-type electronic component is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and other element that oxidizes more easily than iron; the surface of each soft magnetic alloy grain has an oxide layer formed on its surface as a result of oxidization of the grain; this oxide layer contains the other element that oxidizes more easily than iron by a quantity larger than that in the soft magnetic alloy grain; and grains are bonded with one another via this oxide layer. The coil-type electronic component can be produced at low cost and combines high magnetic permeability with high saturation magnetic flux density.
