PROBLEM TO BE SOLVED: To provide an improved turbine blade for a moving blade of a gas turbine which is lighter in weight than all-metal blade, has desirable structure and aerodynamic characteristics, can withstand the entry of foreign matter, and has economic efficiency and erosion and corrosion resistances. SOLUTION: A turbine part 20 comprises a mounting structure 26 for mounting the turbine part, a core 22 made of a structural material which is joined to the mounting structure, and a plastic aerofoil part 24 including at least a part of the core.
