An applicator 100 includes a nozzle 3, the nozzle 3 including a gas channel 53 through which a gas G flows down, a plurality of liquid channels which are provided inside the gas channel 53 and through which each of a first liquid L1 and a second liquid L2 flows down, and a confluence portion 55 which is located on a downstream side of the liquid channels and in which the flows of the liquids join. Of the gas channel 53, a portion between the liquid channels and the confluence portion 55 is configured from a single gas-permeable tube 9 composed of a gas-permeable membrane 93 permeable to the gas G but impermeable to the liquids. The gas-permeable tube 9 is independently connected to the liquid channels, and has a first independent channel 91 and a second independent channel 92 through which the first liquid L1 and the second liquid L2 flow down toward the confluence portion 55 together with the gas G flowing in through the gas-permeable membrane 93. |
