Compressor

A compressor comprising:

• a compression mechanism configured to compress refrigerant;
• a motor unit provided above the compression mechanism, and configured to drive the compression mechanism;
• a shell that houses the compression mechanism and the motor unit;
• and
• an upper insulating member provided above the motor unit,
• wherein the motor unit includes
• a stator fixed to the shell, and
• a rotor spaced from an inner circumferential surface of the stator by a predetermined gap,
• the rotor having a rotor passage that causes spaces located above and below the motor unit to communicate with each other, and
• wherein the upper insulating member is located in a region outward of the inner circumferential surface of the stator and in contact with an inner wall of the shell, and between an outer circumferential surface of the upper insulating member and the inner wall of the shell, an upper insulating-member passage is provided to cause regions located above and below the upper insulating member to communicate with each other.
