Abstract
A turbine wheel () is provided with: a disc () provided so as to be capable of rotating about a center axis (C); and a plurality of blades () provided to a disc surface () at intervals in a circumferential direction, the blades () causing a gas guided in from radially outward leading edges () to be expelled from trailing edges () disposed on one side of each of the blades along the direction of the center axis (C). In each of the blades (), in an area on one side along the direction of the center axis (C) including the trailing edge (), there is provided a concave surface () in which a positive-pressure surface () on the rear side in a rotational direction (R) is recessed forward in the rotational direction (R), causing the gas to be dispersed entirely in the radial direction of the blade ().
