In a scroll compressor that increases the pressure of refrigerant gas and discharges it, the fluid suction port is provided through the counterweight so as to face the circumferential surface of the counterweight, and communicates with a suction passage that directly leads to the compression chamber. A scroll compressor characterized by:
