In the two-stage compressor and a heat pump apparatus using a two-stage compressor, as its object to improve the efficiency of the time the load is small. The heat pump device is provided with a two-stage compressor (100), a first heat exchanger, a first expansion mechanism, a second heat exchanger of the main refrigerant circuit connected in sequence by pipes. Two-stage compressor (100), when the load is higher than a predetermined load, and discharges the refrigerant from the low-stage compression second-stage compressing section 10 and the high-stage compression part 30 to the refrigerant circuit. On the other hand, a two-stage compressor (100), the load in the case lower than the predetermined load, the low-stage compressing section 10 is discharged by the bypass, without compressing the compressed refrigerant in the high-stage compressing section 30 on the main refrigerant circuit do.
