An electrostatic atomizer (50) is provided with a chamber (1) and an air passage (7) which connects a liquid level maintaining hole (5) and an air hole (6) which supplies air to the chamber (1) from the outside of the electrostatic atomizer (50). The electrostatic atomizer (50) is configured in such a manner that the supply of liquid from a liquid supply section (3) to the chamber (1) is stopped when the liquid level maintaining hole (5) is closed. The air passage (7) has a bend section (8). A space (10) for holding liquid is formed in the air passage (7).
