Abstract

To provide a sintered component and a method for producing the same, capable of suppressing a crack that occurs at a recessed corner of a step in a green compact, as well as strength deficiency caused by insufficient density.SOLUTION: A sintered component is obtained by sintering a single green compact made of metal powder and having a step. On a surface of a recessed corner of the step, a brazing material permeates into a gap between the sintered metal powders.SELECTED DRAWING: Figure 2
