The electrostatic atomizing device (10) includes a discharge electrode (20) and an opposed electrode (30) provided with an aperture (31). The opposed electrode (30) has its inner surface (32) opposed to the discharge electrode (20). The inner surface (32) is a recessed surface which surrounds a tip (21) of the discharge electrode (20). The inner surface (32) has at least one part shaped into a spherical surface which is centered on the tip (21) of the discharge electrode (20) and has a constant radius (R). The opposed electrode (30) is provided with a cylindrical electrode (34) extending from a periphery of the aperture (31) away from the discharge electrode (20).
