Abstract
A sintered component forming step is for forming a sintered component by powder molding. An insert forming step is for forming a sintered insert component in which an exterior component is integrated on an outer peripheral portion of the sintered component. One or more grooves or ridges are formed on an outer peripheral portion of a region except for one end portion of the sintered component in the sintered component forming step. The insert forming step includes a step for bringing the outer peripheral portion of the end portion into contact with an inner peripheral surface of an insert forming mold along a circumferential direction and covering the one or more grooves or ridges by the insert forming mold with an interval to form a cavity on an outer peripheral portion of the sintered component and a step for filling a melted material in the cavity.
