Abstract
An impeller including: blades disposed in a circumferential direction of the impeller; a disk located close to a second end side of an axis of the impeller with respect to the blades, to which the blades are attached, and configured to be attached to a rotating shaft; and a shroud located close to a first end side of an axis of the impeller with respect to the blades, and to which the blades are attached. Flow passages are formed by the blades, the disk and the shroud. The blades, the shroud and a first portion of the disk close to the second end side of the axis of the impeller are integrated so as to form a first member. A second portion of the disk close to the first end side of the axis of the impeller forms a second member.
