A rotary compressor, which contains a motor unit and compression mechanism in a sealed case, transmits the rotational power of the motor to the compression mechanism through a rotary shaft and crankshafts eccentrically provided in the rotary shaft, and compresses a refrigerant in the compression mechanism, wherein the rotary compressor is configured to have H/(&phgr;a•E)=K, and K≦̸0.065, and the formula 0.35+0.07•K•H≦̸L/&phgr;Db≦̸0.45+0.07•K•H, assuming that the inside diameter of the cylinder forming the compression mechanism is &phgr;Da [mm], the cylinder height is H [mm], the crankshaft eccentricity is E [mm], the crankshaft diameter is &phgr;Db [mm], and the sliding lengths of the crankshaft and a roller fitted over the crank are set to L [mm].
