Provided is a sprayer which can be used as a cosmetic mist device and an inhaler and includes a tank of a large capacity enough to dispense mist with a sufficient remaining amount of liquid when the sprayer is used heavily. The sprayer includes: an air pump 14; a motor 15; a battery 16; a mist nozzle 12; a tank 13; and a vertically long cylindrical main body case 1 for housing these respective devices. A mist opening 3 is open in an upper portion of a front wall 1a of the main body case 1 and the mist nozzle 12 is disposed on an inner side of the mist opening 3. An inside of the main body case 1 is divided into a front chamber 1A and a back chamber 1B by a division wall 23 and the tank 13 is housed in the front chamber 1A. The air pump 14, the motor 15, and an electrical component section 17 including the battery 16 are disposed in the mentioned order in the back chamber 1B. The tank 13 is formed in a vertically long shape occupying a most part of the front chamber 1A so as to be increased in capacity without affecting an outer shape of the main body case 1. A grip portion 5 is formed in a recessed manner at an upper portion of a back face of the main body case 1 and the air pump 14 and the motor 15 are disposed near the grip portion 5.
