Summary:PROBLEM TO BE SOLVED: To enhance joining strength of a blade and a disk or cover. SOLUTION: The cover and the blade 3 oppositely arranged on the disk 2 are integrally molded, and after forming a groove 5 corresponding to a blade shape on a blade installation surface (a surface 2a) of the disk 2, a brazing material 6 is arranged in a bottom part 5a of its groove 5, and then, the blase edge 3a of the blade 3 integrally molded in the cover is inserted into its groove 5, and the bottom part 5a of a tapered groove 5 and the blade edge 3a are joined by the brazing material 6, and an impeller is manufactured thereby without making the brazing material 6 put in a liquid phase state by heating, flow out of the groove 5.
