Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a channel wall used as a boundary of a high-temperature combustion gas in a gas turbine engine. SOLUTION: This wall includes an outer face 36 and an inner face 40 opposite to each other, and a plurality of cooling holes 42 extended between the outer face and the inner face. A heat barrier film 48 is adhered onto the outer face to cover the holes to be blind holes. The high-temperature combustion gas 18 is passed on the heat barrier film 48, the cooling air is passed on the inner face 40 and into the blind holes 42, and the fracture of the heat barrier film occurs when a temperature is over the temperature performance of the heat barrier film, whereby the outlets 46 of the holes are opened, and the film cooling gas flow is passed through the opened holes.
