PROBLEM TO BE SOLVED: To enhance efficiency by improving pressure loss of a gas turbine comprising an outlet guide vane and a diffuser. SOLUTION: In this gas turbine, the diffuser is arranged to a downstream side of a final stage moving blade, and the plural outlet guide vanes are arranged between the final stage moving blade and the diffuser so as to surround a center axis of the gas turbine. In this gas turbine, a height of a trailing edge blade is set larger than a height of a leading edge blade of the outlet guide vane, and an inflow speed of a drive gas of an inlet of the diffuser is made lower than an outflow speed of the drive gas at an outlet of the final stage moving blade. Accordingly, the pressure loss of the diffuser is reduced, and a turbine efficiency is enhanced.
