摘要： It is an object of the present invention to effectively suppress the overflow of brazing material from each joint of a sinter-brazed component, such as a planetary carrier, obtained by brazing a plurality of members together. According to the present invention, there is provided a sinter-brazed component obtained by mating and joining a first member having a first bonding surface and a second member having a second bonding surface to each other. Brazing material is provided between the first bonding surface and the second bonding surface. The first bonding surface has a first recess, the first recess having an inner peripheral wall and a bottom surface. The inner peripheral wall extends along and on an inner side of a profile line of the first bonding surface.
