PROBLEM TO BE SOLVED: To provide a gas turbine member that protects a surface of the member from a combustion gas with an effective use of a cooling medium to suppress reduction in the performance of a gas turbine.SOLUTION: The gas turbine member includes: a base material 51; a recess 54 formed on a surface of the base material 51; an air inlet 53 arranged in the recess 54; and a heat shield film 52 supported by the base material 51 to cover a first region 61 on the surface of the base material 51 around the recess 54, and having an overhang part 52H which makes the recess 54 overhang from the first region 61 and faces the air inlet 53 at a position apart from the air inlet 53. The first region 61 is arranged at one side in a first direction substantially parallel to the surface of the base material 51 with respect to the recess 54, and the overhang part 52H extends to the other side in a first direction.
