PROBLEM TO BE SOLVED: To provide a radial turbine improving a turbine efficiency by restraining enlargement of a low speed area due to exfoliation of a flow in an impeller flow path, and a loss due to collision of an inflow gas and a moving blade leading edge. SOLUTION: In this radial turbine, gas flown from a radial direction flows to an impeller mounted to a plurality of moving blades 2 in an axial direction. Arc faces 2a, 2a having a radius R of a dimension of 50% or less of a thickness t of the moving blade 2 are formed in a crossing part of a leading edge 2-1 of the moving blade 2, and a pressure face 2-2 and a negative pressure face 2-3.
