PROBLEM TO BE SOLVED: To provide a liquid spray device capable of stabilizing spraying with a simple structure at low costs, and to provide a cosmetic liquid spray device.SOLUTION: A cosmetic liquid spray device (1) includes: a tank (3) composed of a cylindrical protruding part (31) which has a liquid supply port (33) and is formed protruding and a liquid holding part (32) which holds the liquid (7); a case (2); an elastic diaphragm (4) which is supported by the case (2), is attached to the liquid supply port (33), and has a number of micropores; and an ultrasonic vibrator (5). The ultrasonic vibrator (5) causes ultrasonic vibrations in the elastic diaphragm (4) and a liquid (7) stored in the tank (3) is sprayed from the liquid supply port (33) through the number of micropores of the elastic diaphragm (4). An air circulation hole (30) which allows the interior of the tank to communicate with the exterior is formed at the cylindrical protruding part (31) of the tank (3). A bore diameter of the air circulation hole (30) is formed so as to be larger than a bore diameter of each micropore of the elastic diaphragm (4). |
