Beschreibung
Zusammenfassung:	A blade (50) is formed with blade air passages (71) connecting the inside of a blade body (51) of the blade (50) and the inside of a platform (61) of the blade (50). The platform (61) is formed with a plurality of pressure side passages (72) that extend from the blade air passages (71) toward a circumferential pressure side, are open at a pressure side end face (64), and are arranged in an axial direction (Da). Further, the platform (61) is formed with a suction side main passage (73) into which cooling air flows, and a suction side passage (74) that communicates with the suction side main passage (73) and extends from the suction side main passage (73) along a suction side end face (65).
