摘要：
A centrifugal compressor includes an impeller, a diffuser flow passage forming portion forming an annular diffuser flow passage on a downstream side of the impeller, a plurality of small chord-pitch ratio diffuser blades disposed in the diffuser flow passage at intervals in a circumferential direction of the impeller, and a flow passage dividing annulus extending to the diffuser flow passage along a radial direction of the impeller, and dividing the diffuser flow passage into a hub-side flow passage and a shroud-side flow passage.
