SOFT MAGNETIC PARTICLE POWDER, SOFT MAGNETIC RESIN COMPOSITION, SOFT MAGNETIC FILM, SOFT MAGNETIC FILM LAMINATE CIRCUIT BOARD AND POSITION DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide: soft magnetic particle powder by which a soft magnetic film having good relative magnetic permeability can be manufactured readily; a soft magnetic resin composition arranged by use of such soft magnetic particle powder; a soft magnetic film; a soft magnetic film laminate circuit board; and a position detector.SOLUTION: Soft magnetic particle powder is composed of flat soft magnetic particles. A particle diameter Dand a particle diameter Dmeasured by a laser-diffraction type particle-size-distribution-measurement device satisfy the following expression: D/D0.30.
