To reduce non-uniformity in flow velocity of working fluid current that occurs in a passage between blades of turbine cascade on the downstream side in order to obtain axial turbine cascade with improved turbine efficiency, by wake discharged from the turbine cascade.

An axial turbine cascade 10 is arranged in peripheral direction with its blade root portion fixed to blade end wall. The shape of a trailing edge line 7 in vertical direction that forms the rear end of the turbine blade 1 constructing the multiple-stepped turbine cascade in the axial direction of the turbine rotor, is provided in wave-shape having swell in peripheral direction of the turbine cascade. This accelerates diffusion of wake discharged from the trailing edge of the turbine moving blade, and staggers inflow timing of the wake, that flows into the turbine cascade on the downstream side, in the vertical direction of the turbine blade. Therefore, unsteady decrease in effective passage area of the passage between blades of turbine cascade on the downstream side is reduced, and the energy of working fluid is effectively used for driving the turbine cascade.
