In a multistage rotary compressor using a refrigerant such as carbon dioxide (CO2) and the like which becomes high in a discharge pressure, operating efficiency thereof can be enhanced by appropriately setting the ratio between displacement of the respective rotary compression elements and the areas of discharge ports thereof. In the multistage rotary compressor comprising an electric element in a hermetic shell case, and first and second rotary compression elements which are driven by the electric element, wherein a refrigerant which is compressed and discharged by the first rotary compression element is drawn into and compressed by the second rotary compression element and discharged thereby, wherein the ratio of S2/S1 is set to be smaller than ratio of V2/V1, where S1 is an area of a discharge port of the first rotary compression element, S2 is an area of a discharge port of the second rotary compression element, V1 is displacement of the first rotary compression element, and V2 is displacement of the second rotary compression element.
