PROBLEM TO BE SOLVED: To improve the turbine efficiency of an axial flow turbine of low boss ratio. SOLUTION: In order to reduce the Mach number in the steam flowing into a final stage rotor blade 24 from a final stage stator blade 28 of the axial flow turbine 10, the final stage rotor blade 24 and a rotor blade 26 on the upstream side by one stage of the final stage rotor blade 24 are arranged so that the line L to connect a leading edge root 24a of the final stage rotor blade 24 to a trailing edge root 26a of the rotor blade 26 on the upstream side by one stage of the final stage rotor blade 24 is inclined on a rotor 12 side.
