Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing a magnetic member that can be increased in density, increased in real number part μ'(13.56 MHz)of complex relative permeability, and made high in surface resistance effectively more than before. SOLUTION: The method of manufacturing the magnetic member includes at least one of a step (a) of forcibly dispersing Fe-group soft magnetic alloy powder under pressure into a mixed material, the mixed material being prepared by mixing the Fe-group soft magnetic alloy powder and a matrix material, and a step (b) of leaving them as they are for a predetermined time before molding the mixed material.
