Abstract
An impeller for a centrifugal rotary machine has a plurality of blades (4) arranged at intervals in a circumferential direction on a face facing a direction of an axis of a disc (3) formed in a discoid shape about the axis, wherein the blades (4) each include a first section (10A) rising from the disc (3) and inclined toward an opposite direction of a rotary direction (R) as the distance from the disc and a second section (11A) continuing from the first section (10A) and inclined toward a forward direction of the rotary direction (R) as the distance from the disc (3) between the leading edges and the trailing edges in the blades (4).
