PROBLEM TO BE SOLVED: To compose a high-low pressure dome type compressor in a compact form and efficiently cool a drive motor. SOLUTION: On a scroll type compression mechanism (15), a communication passage (46) having a discharge port (49) for flowing out a refrigerant compressed by the compression mechanism (15) to a gap space (18) between the compression mechanism (15) and the drive motor (16) is formed. In the compression mechanism (15), a muffler space (45) communicated with the communication passage (46) and eliminating operation noise is formed. A motor cooling passage (55) for flowing working fluid flowing out to the gap space (18) is formed between the drive motor (16) and an inner face of a casing (10). A guide plate (58) is arranged in the gap space (18). On the guide plate (58), a branch flow recessed part for making part of the refrigerant flowing toward the motor cooling passage (55) flow in the circumferential direction and flow toward an inner end part (36) of a discharge pipe (20) positioned in the gap space (18) is formed.
