PROBLEM TO BE SOLVED: To provide a turbine blade improving profile efficiency by reducing loss due to shock wave and loss due to deficit of velocity distribution of slip stream. SOLUTION: In a turbine blade having a shape of a following edge 2 in a profile 1 formed with a ventral side edge line 3 and a dorsal side edge line 4, the ventral side edge line 3 is formed with either straight line or curved line having large curvature radius and the dorsal edge line 4 is formed with curved line having smaller curvature radius than curvature radius of the ventral side edge line 3, angle formed at a connection point of an end part of the ventral side edge line 3 and an end part of the dorsal side edge line 4 is formed in roughly perpendicular.
