1. A method of manufacturing a sintered body comprising:
a debindering process of carrying out a debindering to an injection molded body produced by a primary shaping by injecting into an injection mold a shaping material in which a metal powder and a binder are mixed, to produce an intermediate shaped body;
a sintering process of carrying out a sintering to the intermediate shaped body to produce a sintered body; and
a secondary shaping process of transforming the injection molded body or the intermediate shaped body before the sintered body is produced,
wherein the secondary shaping process includes a process of grasping a first part and a second part of the injection molded body or the intermediate shaped body, and rotating the first part and the second part relatively to apply torsion transformation to the injection molded body or the intermediate shaped body.
