Title:
INSULATOR CONTAINING MAGNETIC ELEMENT AND CIRCUIT BOARD AND ELECTRONIC APPARATUS USING IT
Document Type and Number:
WIPO Patent Application WO/2006/101031
Kind Code:
A1
Abstract:
An insulator containing a magnetic element capable of effectively increasing permeability without comparatively increasing the mixture concentration of magnetic elements, and enhancing characteristic impedance by applying a magnetic element-containing insulator thus obtained to a circuit board, and providing a low power consumption effect; and a circuit board and an electronic apparatus using it. The magnetic element-containing insulator (10) comprises a plurality of magnetic element particles (1a, 1b) and insulators (2) holding the plurality of magnetic element particles (1a, 1b), wherein the magnetic element particle groups are composed of at least a plurality of particle sizes.
