A capacity-controlled scroll-type compressor having an internally-bypassing system is provided, by which when the capacity is controlled, it is possible to prevent the tip gaps near the gas-suction inlet (44) or the main stream of a bypassing gas from becoming smaller than those of other portions. Regarding the tip gaps near the gas-suction inlet, the length of teeth of a portion of the scrolls (10, 14), which is closer to the gas-suction inlet, is shorter than teeth of other portions of the scrolls. Regarding the tip gaps near the main stream of a bypassing gas, (i) the length of teeth of a portion of the scrolls, which is close to the main stream of a bypassing gas, is shorter than teeth of other portions, or (ii) a gas-suction inlet is positioned near the main stream of a bypassing gas so as to suppress increase in the temperature of an area neighboring the main stream of the bypassing gas.
