Method of manufacturing compressor, and compressor

This compressor is provided with a housing (30) formed in a cylindrical shape, a compression mechanism (10) which is placed in the housing, and which has a fixed member (12) and a movable member (11), and a plurality of external connection pipes (310-313) each forming a flow channel that causes the external side of the housing to be in communication with the compression mechanism. The plurality of external connection pipes are arranged so as to be point-symmetric around an axial line (S) of the housing or are placed so as to be arranged in the circumferential direction at equal intervals. When the plurality of external connection pipes are press-fitted in and engaged with holes (128, 121a, 124, 129) of the fixed member, the plurality of external connection pipes are arranged in a positional relationship that offsets the pressure load from each other.
