Abstract
A film cooling structure includes a wall surface which faces a gas-flow passage for high-temperature gas. One or more than one pair of jetting holes are formed on the wall surface so as to respectively jet cooling media into the gas-flow passage. The pair of jetting holes respectively have jetting directions in which the cooling media are jetted from the pair of jetting holes into the gas-flow passage. The jetting directions of the pair of jetting holes are respectively set so as to respectively form swirls in directions in which the cooling media are mutually pressed against the wall surface.
