PROBLEM TO BE SOLVED: To provide the manufacturing method of a compound magnetic component having higher permeability by forming an interface layer generated by the mutual diffusion of atoms in a boundary between a metallic magnetic particles and a ferrite film to reduce air gaps, and improving chemical unity to facilitate the formation of a magnetic path. SOLUTION: The manufacturing method of the compound magnetic component consisting of metallic magnetic particle and ferrite comprises (1) a process for coating the metallic magnetic particles by ferrite, (2) a compression forming process for forming the obtained ferrite-coated metallic magnetic particles into a thin sheet with the thickness of 5 mm or less, and (3) a heat treatment process for effecting the heat treatment of the obtained formed body by heating the same uniformly from the front and rear surfaces thereof, in which process, the highest achieved temeprature is 500°C or above, and the temperature of 500°C or above is maintained for five minutes or less.
