PROBLEM TO BE SOLVED: To provide a radial turbine with high turbine efficiency, hardly producing chipping. SOLUTION: A front end face 25 including a leading edge 24 of a turbine blade is smoothly curved on the blade section along the direction of flow of a high temperature gas G flowing in rows of turbine blades 22. It is preferable that the part from the front end face 25 to the frond end part 28a of the upper edge of the turbine blade 22 is formed as a smooth curved part viewed from the direction P orthogonally crossing the blade face 22a. Moreover, it is preferable that the part from the front end face 25 to the front end part 27a of the lower edge of the turbine blade 22 is formed as a smooth curved part viewed from the direction P orthogonally crossing the blade face 22a.
