Claim 6:
7. A compressor comprising:
a motor unit that includes a rotor and a stator surrounding the rotor;
a compressor unit that compresses a refrigerant by rotation of the rotor; and
a container that forms an internal space in which the motor unit and the compressor unit are housed,
wherein in the rotor, a rotor gas passage through which the refrigerant flows from an under-motor space of the internal space that is arranged on a side of the motor unit that is close to the compressor unit to an above-motor space of the internal space arranged on a side of the motor unit that is distant from the compressor unit is formed,
in the stator, a stator gas passage through which the refrigerant flows from the under-motor space to the above-motor space is formed,
the stator gas passage includes a stator outer circumferential gas passage formed between the stator and the container, and
a cross-sectional area of the stator outer circumferential gas passage is 1.2 to 1.6 times a cross-sectional area of the rotor gas passage.
