A gas turbine blade comprising: a hollow blade form portion (17) formed by a leading edge (19) on an upstream side of an working fluid of a gas turbine in a flow direction, a trailing edge (20) on a downstream side of the working fluid in the flow direction, and a suction surface and a pressure surface reaching the trailing edge (20) from the leading edge (19), and a shank portion for supporting the blade form portion (17), characterized in that, the gas turbine blade (2, 4, 6) is further comprising: a plurality of coolant paths (204a-204h) formed by the partitions (210a-210b), said flow paths being connected by convrter portions (205a, 205b), and an outer peripheral side plate (214) made of a different member from the blade form portion (17) is attached on an outer peripheral side of the blade form portion (17) and defines outermost peripheral ends of the first flow path (204a) and the second flow path (204b). Corresponding gas turbine and manufacturing method are also provided. |
