Abstract

A hot part () of a gas turbine includes a planar member having a gas path surface () that faces at least one of an inner side and an outer side in a radial direction of the rotor in a combustion gas flow path. A cooling flow path is formed in an interior of the planar member along an outer peripheral surface () that intersects the gas path surface (). The planar member has an outer peripheral surface side turbulator () that protrudes from an inner surface on an outer peripheral surface () side of the cooling flow path.
