ABSTRACT:
A vane member comprises a first member and a second member, the first member and the second member are joined by that an insert member whose melting temperature is lower than melting temperatures of the first and second members contacts the first and second members, the insert member is heated to a welding temperature which is lower than the melting temperatures of the first and second members and is higher than the melting temperature of the insert member so that a mutual diffusion between at least an original base component of the insert member and at least an original base component of the first member different from the original base component of the insert member and a mutual diffusion between at least the original base component of the insert member and at least an original base component of the second member different from the original base component of the insert member are caused by the heating, and the mutual diffusions by the heating are continued at least until the original base component of the insert member is replaced by at least one of the original base components of the first member and the second member and the at least one of the original base components of the first member and the second member becomes a substitute base component of the insert member.
