An electrostatic spraying device (1) includes a tank (11) in which a liquid is stored, a gas supply path (6a) which communicates with the tank (11), a pump (2) which applies pressure to the liquid in the tank (11) by supplying air to the tank (11) via the gas supply path (6a), and a control section (4) which controls a supply operation of the pump (2) to adjust a pressure in the tank (11). |
