ABSTRACT:
A plurality of film cooling holes13is formed at regions exposed to a hot gas in a turbine component main body3, each of the film cooling holes13is comprised of a straight hole portion15formed at a portion at a side of an inner wall surface5aof the turbine component main body3and a diverging hole portion17formed at a portion at a side of an outer wall surface5bof the turbine component main body3, and further each of the film cooling holes13is so constituted that an outlet surface17pof the diverging hole portion17from a center portion to both end sides in a lateral direction L3gradually to a great extent leans toward a downstream side of the hot gas on the basis of a hypothetical plane VP parallel to two directions of an axial center direction L2and a lateral direction L3of the straight hole portion15.
