To provide a compressor excellent in startability by reducing start torque while preventing a device from getting upsized.

This hybrid compressor is provided with a first compression mechanism and a second compression mechanism including exclusive drive sources respectively and being selectively or simultaneously driven, and has fluid compressed by each compression mechanism delivered to same delivery chamber via exclusive first delivery passage and a second delivery passage. A fluid introduction mechanism introducing a part of delivery fluid from a delivery side of the first compression mechanism driven by a drive source generating large drive torque to a second delivery passage at the time of the second compression mechanism driven by a drive source generating small drive torque is stopped is provided.
