摘要：
A partially hardened sintered body such as a rocker arm comprises powder forming a main body and a capsule-like powder composite disposed adjacent to the powder and composed of core particles made of a material harder than the powder and covering particles covering the core particles and made of the same material as the powder. The powder and the capsule-like powder composite are solidified into the partially hardened sintered body.
