PROBLEM TO BE SOLVED: To provide a turbine blade cooling a tip shroud, and also reducing weight of the tip shroud. SOLUTION: This turbine blade 10 includes the tip shroud 20 and one or more of cooling cavities 130 formed in the tip shroud 20. At least one of the cooling cavities 130 includes a plurality of ribs 142 and 144 and a first inner wall substantially opposed to a second inner wall over the cooling cavities 130. The ribs 142 and 144 are constituted so that several of the ribs 142 and 144 extend toward the second inner wall of the cooling cavities 130 by starting on the first inner wall of the cooling cavities 130 and several of the ribs 142 and 144 extend toward the first inner wall of the cooling cavities 130 by starting on the second inner wall of the cooling cavities 130. The ribs 142 and 144 starting on the first inner wall of the cooling cavities 130 and the ribs 142 and 144 starting on the second inner wall of the cooling cavities 130, include alternate arrangement.
