COMPOSITE MATERIAL MOLDED BODY, REACTOR, AND METHOD FOR MANUFACTURING COMPOSITE MATERIAL MOLDED BODY

Document Type and Number:

WIPO Patent Application WO/2017/119439

Kind Code:

A1

Abstract:

A composite material molded body comprising a soft magnetic powder and a resin encapsulating the soft magnetic powder in a dispersed state, wherein, of the surface of the composite material molded body, when the composite material molded body is divided into a total of nine portions so that a linkage plane intersecting magnetic flux excited in the composite material molded body is divided into three equal parts longitudinally and laterally, of these portions, a density decrease ratio Dd = {(Dmax - Dmin)/Dmax} × 100 of a portion with a minimum density Dmin with respect to a portion with a maximum density Dmax is not more than 1.8%.
