Abstract

A compressor includes a motor unit that includes a rotor and a stator, 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 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, and a cross-sectional area of the stator gas passage is 6.0 times or less a cross-sectional area of the rotor gas passage.
