COMPOSITE MATERIAL, METHOD FOR MANUFACTURING THE SAME, MAGNETIC CORE, AND COIL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a composite material and a method for manufacturing the same to ensure excellent manufacturing cost and productivity in order to improve the target volume occupation rate without use of a large amount of powder having fine grain size. SOLUTION: In a composite material formed of resin and powder, a second powder formed of spherical particle having the average grain size of 1/400 to 1/20 of the average grain size of a first powder occupying the greater part of the powder is added in the volume percentage of 1 vol% or more to the composite material.
