To prevent a liquid backflow phenomenon from occurring that a liquid-form working-fluid is led to a compression mechanism, in a hermetic compressor that once retains low-pressure working-fluid in a hermetically-sealed case and guides the working fluid to the compression mechanism arranged in the hermetically-sealed case, and then compresses the working fluid.

The hermetic compressor 2 includes a motor section 8 and a compression mechanism 9 which are housed in the hermetically-sealed case 7, and a rotating shaft 12 for coupling the motor section 8 and the compression mechanism 9 together is formed with a suction passage 26 for guiding the working fluid inside an upper space A of the hermetically-sealed case 7 to the compression mechanism 9. The suction section 26a of the suction passage 26 that opens inside the upper space A is located above an exit section 31a that opens in the upper space A in a suction pipe 31 for guiding the working fluid to the upper space A.
