Disclosed is a dehumidifier capable of dehumidifying an indoor space more efficiently. The present dehumidifier comprises: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body so as to draw air into the body through the intake opening and to discharge the same to the outside through the discharge opening; a fan case having a duct arranged inside the body so as to provide a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body so as to remove moisture from the air that has flown into the body; and fixed blades that are fixedly installed inside the duct so as to split the air, which has flowed through the channel, to a plurality of discharge paths.
