A sprayer capable of avoiding clogging caused in the nozzle includes liquid supplies for supplying a liquid, and a nozzle connected to the liquid supply. The nozzle includes a first internal tube and a second internal tube through which a first liquid and a second liquid supplied from the liquid supply pass, respectively, and an external tube into which respective internal tubes are inserted, and which allows a gas to pass through the gap between it and each internal tube, for ejecting the first liquid and the second liquid with the gas. At least a part of the longitudinal direction of each internal tube is formed of a coil including a helically wound wire rod, so that the gas can flow into the inside of the coil from between the adjacent portions of the wire rod of the coil.
