Abstract
A radial turbine impeller includes a hub having a substantially conical shape and multiple turbine blades provided on an outer peripheral surface of the hub at intervals in a rotational direction. In a meridian cross section, a hub line formed by the outer peripheral surface of the hub has a diameter that monotonically decreases from an upstream end on a radially outer side to a downstream end on a radially inner side, and includes a convex part that is convex toward a radially outer side.
