Provided is a gas turbine wherein an axial space between a stator vane and a rotor vane and the end faces of the vanes can be effectively cooled. In the gas turbine wherein the difference between the number of vane portions of a second stage stator vane and a third state stator vane is zero, the relative position between the second stage stator vane and the third stage stator vane in the circumferential direction is determined so that a slipstream generated by the vane portion of the second stage stator vane is introduced by clocking to the front edge of the vane portion (17) of the third stage stator vane within an area of the vane portion (17) of the third stage stator vane, which occupies 0% or more and 15% or less of the length of the vane portion in the span direction from the side facing a hub. |
