Title:
COIL-TYPE ELECTRONIC COMPONENT AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/136198
Kind Code:
A1
Abstract:
Provided is a coil-type electronic component formed using a magnetic material which can be produced at low cost and combines high magnetic permeability with high saturated magnetic flux density. The coil-type electronic component comprises a base structure and a coil disposed inside the structure or on the surface thereof. The base structure of the coil-type electronic component is configured from particles of a soft-magnetic alloy comprising iron, silicon, and an element that is more oxidizable than iron. The particles of the soft-magnetic material have an oxide layer formed on the surface thereof by oxidation of the particles. The oxide layer contains the element which is more oxidizable than iron, in a larger proportion than the alloy particles. The particles have been bonded to one another through the oxide layer.
