In S, after preforming a pressed powder member by compressing metal powder filled in a press-forming portion, the pressed powder member and metal member are slid to each other in S. In S, after temporarily joining the pressed powder member and the metal member by further pressurizing the powder member, the temporary joined pressed powder member and the metal member are sintered in a sintering furnace, and the pressed powder member and the metal member are joined by sintering diffusion in S. Thereby, joining areas between the pressed powder member and the metal member are increased, and it is possible to improve a joining strength between the pressed powder member and the metal member.

A blade inspection apparatus has a borescope and a PC. The borescope has a distance sensor for detecting an insertion length when an insertion section of the borescope is inserted through a hole provided in a casing in which a rotor of an engine is housed, an acceleration sensor for detecting an attitude of the insertion section, and distance sensors for detecting two distances from the insertion section to two stator vanes on a stator. The PC compares the attitude and two distances detected in the borescope with the attitude and two distances relating to an inspection image stored in a HDD. When a match occurs therebetween, the PC outputs match information.
