PROBLEM TO BE SOLVED: To achieve miniaturization of a helical compressor and restraining a higher temperature of an electric motor. SOLUTION: A disk shaped front side closing body 12 is joined to a front end surface of a cylinder 11, and a disk shaped rear side closing body 13 is joined to a rear end surface of the cylinder 11. The cylinder 11, the front side closing body 12 and the rear side closing body 13 constitute a whole housing 10. A part of refrigerant gas in an external refrigerant cooling circuit flows into the cylinder inside 181 of a rotating body 18 through a communication port 28, a connection groove 29 and an inflow path 30. The gas flowing into the cylinder inside 181 flows to a compression region So near an intake path 132 through an outflow path 31 and a communication port 32.
