A compressor includes a compression mechanism, an electric motor unit, a drive shaft and a housing. A portion of the drive shaft, which is located on one side in an axial direction, is rotatably supported by a main bearing, which is formed integrally in one-piece with or is fixed to a main bearing member of the compression mechanism. Another portion of the drive shaft, which is located on another side in the axial direction, is rotatably supported by a sub-bearing, which is formed integrally in one-piece with or is fixed to an inside of a body portion of a sub-bearing member. The sub-bearing member is formed separately from the housing and is fixed to a bottom surface of a bottom portion of the housing.
