An impeller includes a disk that has a disk shape centered on an axis, a cover that is disposed to be separated from the disk in an axial direction in which the axis extends, a plurality of blades that connect the disk and the cover to each other and are disposed at intervals in a circumferential direction around the axis, and a connection member that is disposed to be separated from the plurality of blades in the axial direction and connects the disk and the cover to each other. A plurality of the connection members are disposed at intervals in the circumferential direction at positions near an inlet of an impeller flow path with respect to front edges of the blades positioned at positions near the inlet, the impeller flow path being formed between the disk and the cover.
