摘要

A flow path forming plate (60i) is provided with a plate body (61i), a peripheral wall (65i), and a shelf (71). The plate body (61i) includes: a gas-path surface (64p) facing a gas flow path side; and an inner surface (64i) facing a side opposite to the side which the gas-path surface (64p) faces. The peripheral wall (65i) protrudes from the inner surface (64i) toward a side opposite to the flow path, along the peripheral edge of the plate body (61i). The shelf (71) protrudes from the inner surface (64i) toward the side opposite to the flow path, along an inner wall surface of the peripheral wall (65i). The shelf (71) receives an impinging plate (81) having a plurality of through-holes (82) therein. The shelf (71) is disposed only on a part of the inner wall surface of the peripheral wall (65i).
