Document Type and Number:
WIPO Patent Application WO/2014/148311
Kind Code:
A1
Abstract:
Provided is a coil module that can be reduced in size and thickness as a result of the incorporation of a material and structure that resist magnetic saturation. Said coil module is provided with a magnetic-grain-containing magnetic resin layer (4a) and a spiral coil (2). The magnetic resin layer (4a) contains magnetic grains that either are spherical or are spheroidal with an aspect ratio, expressed as the quotient of the major diameter and the minor diameter, of 6 or less.
