Abstract
A compressor includes: an impeller including a hub and a plurality of blades disposed on an outer surface of the hub; and a housing which houses the impeller. The housing includes: a shroud section facing the outer surface of the hub to form a fluid flow path between the shroud section and the outer surface, and surrounding the impeller; and a casing section formed integrally with the shroud section and supporting the shroud section. The shroud section includes a first resin-based material having a static tensile strength of at least 65 MPa and no more than 200 MPa and a breaking strain of no more than 0.3 mm/mm at a temperature of 100° C. The casing section includes a second resin-based material having a static tensile strength of at least 40 MPa and a breaking strain of at least 0.1 mm/mm at a temperature of 100° C.
