Abstract:
The invention is directed to a method of manufacturing a green compact. The method includes a filling step of filling a compacting space with an insulated coated soft magnetic powder. The compacting space is defined by a die. The die has a through hole with which a part of the outer circumferential surface of the green compact is molded. The die also has a core rod with which another part of the outer circumferential surface of the green compact is molded, and a first punch disposed so as to cover one of opening portions of the through hole, the core rod being inserted and disposed in a space of the through hole. The method also includes a pressurizing step using the first punch and a second punch disposed so as to face the first punch. The method also includes a removing step.
