A compressor is used in an automotive air conditioner to compress a refrigerant gas. The compressor includes a first compression mechanism driven by an automobile engine and a second compression mechanism driven by an electric motor. The first and the second compression mechanisms are connected in series to each other with respect to a flow of the refrigerant gas. Preferably, the first compression mechanism is disposed on a downstream side of the second compression mechanism with respect to the flow of the refrigerant gas.
