There is provided a two-stage compression rotary compressor in which the balancer mass of a rotor can be made as small as possible, and the moments that tilt the whole of a shaft can be balanced. The axial length L 2 of a high-stage side crankshaft 72 corresponding to a high-stage compressing section 32 is longer than the axial length L 1 of a low-stage side crankshaft 73 corresponding to a low-stage compressing section 31 (L 2 >L 1 ).
