PURPOSE: A drain pump of an air-conditioner is provided to prevent the operational noise of a pumping motor because the pressure face of an impeller, which pushes condensate during a pumping operation, is concaved. CONSTITUTION: A drain pump of an air-conditioner comprises a pumping motor(40), a pump housing(110), a pumping operation unit(100), a guide body(123), and an impeller(125). The pumping motor is arranged on the upper side of a condensate collecting part. The pump housing has a condensate inlet and a condensate outlet on the right or left side. The pumping operation unit draws in the condensate collected in the condensate collecting part through the condensate inlet and discharges the condensate through the condensate outlet. The guide body guides the condensate which flows from the condensate inlet to the condensate outlet. The impeller has a concave face which pushes the condensate during the rotation.
