A discharge chamber (23) into which a refrigerant compressed by a compression mechanism section (4) is discharged is provided within a housing (100). A resonator (30) is connected to the portion (270a) of a connection passage (270) which is located between the ends thereof, the connection passage (270) connecting the discharge chamber (23) and the discharge opening (27) of the housing (100). The resonator (30) has a resonance chamber (32) and an introduction passage (31). One end (31c) of the introduction passage (31) is connected to the portion (270a) of the connection passage (270) which is located between the ends thereof, and the other end (31d) of the introduction passage (31) is connected to the resonance chamber (32). |
