A turbine blade that is capable of being cooled by a coolant gas supplied to a hollow region of the turbine blade, the turbine blade comprising: a pressure wall surface; a suction wall surface; the hollow region; pressure side protruding portions protruding from the pressure wall surface of the hollow region, end faces of the pressure side protruding portions being separated from the suction wall surface; suction side protruding portions protruding from the suction wall surface of the hollow region, end faces of the suction side protruding portions being separated from the pressure wall surface; and a plurality of meandering flow paths, formed by the pressure side protruding portions and the suction side protruding portions being alternately arranged, that guide the coolant gas between the suction wall surface and the pressure wall surface, while causing the coolant gas to repeatedly meander, continuously arranged from a hub side toward a tip side of the turbine blade, the meandering flow paths adjacent to each other causing the coolant gas to meander in different repetitive patterns, characterized in that when a direction, in which the hub side of the turbine blade is connected to the tip side of the turbine blade, is a height direction of the turbine blade, a bottom or a top in the height direction of the pressure side protruding portions and the suction side protruding portions of a first one of the plurality of meandering flow paths is located at the same height of the turbine blade as a respective top or bottom in the height direction of the pressure side protruding portions and suction side protruding portions of a second one of the plurality of meandering flow paths, and the second one of the plurality of meandering flow paths is adjacent to the first one of the plurality of the meandering flow paths. a pressure wall surface; a suction wall surface; the hollow region; pressure side protruding portions protruding from the pressure wall surface of the hollow region, end faces of the pressure side protruding portions being separated from the suction wall surface; suction side protruding portions protruding from the suction wall surface of the hollow region, end faces of the suction side protruding portions being separated from the pressure wall surface; and a plurality of meandering flow paths, formed by the pressure side protruding portions and the suction side protruding portions being alternately arranged, that guide the coolant gas between the suction wall surface and the pressure wall surface, while causing the coolant gas to repeatedly meander, continuously arranged from a hub side toward a tip side of the turbine blade, the meandering flow paths adjacent to each other causing the coolant gas to meander in different repetitive patterns, characterized in that when a direction, in which the hub side of the turbine blade is connected to the tip side of the turbine blade, is a height direction of the turbine blade, a bottom or a top in the height direction of the pressure side protruding portions and the suction side protruding portions of a first one of the plurality of meandering flow paths is located at the same height of the turbine blade as a respective top or bottom in the height direction of the pressure side protruding portions and suction side protruding portions of a second one of the plurality of meandering flow paths, and the second one of the plurality of meandering flow paths is adjacent to the first one of the plurality of the meandering flow paths.
