Patent ID: 8704629

Claim:
A coil-type electronic component having a coil provided inside or on a surface of a base material, wherein: the base material is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and chromium 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 by heat treatment in an atmosphere containing oxygen; the oxide layer contains more chromium than does the alloy grain; and the grains are bonded with one another via the oxide layer, wherein the oxide layer includes in this order a first oxide layer where the content of the iron component decreases while the content of chromium that oxidizes easily increases, and a second oxide layer where the content of the iron component increases and the content of chromium that oxidizes easily decreases, as viewed outwardly from the soft magnetic alloy grain.
