Beschreibung
Zusammenfassung:	Provided is a flow path forming plate having a gas path surface (64p) that comes in contact with combustion gas, end surfaces formed at peripheral edges of the gas path surface (64p), a first side passage (90i), and a plurality of end surface blow-out passages (71). The first side passage (90i) extends in a direction along a first end surface (62b) that is one of the end surfaces, and cooling air (Ac) flows through the first side passage (90i). A plurality of passage forming surfaces forming the first side passage (90i) includes a first forming surface (91) that faces an opposite-flow-path side (Dri) and extends gradually farther away from the gas path surface (64p) while extending toward the first end surface (62b). The end surface blow-out passages (71) open in the first forming surface (91) of the first side passage (90i) and in the first end surface (62b).
