Electrostatic spray device, cartridge, and cover

A hand-held type electrostatic spray device which has a shape or a size that a user is capable of retaining with a hand and sprays an electrically charged liquid, the electrostatic spray device comprising:

• a voltage source;
• a base electrode for electrically charging the liquid to which a voltage is applied from the voltage source and which includes a linear tip portion;
• an additional electrode to which a voltage is applied from the voltage source;
• and
• two or more conductors which are electrically isolated from the base electrode and the additional electrode and are disposed apart with respect to the additional electrode in a spray direction of the liquid,
• wherein at least a part of the two or more conductors overlaps with the additional electrode viewed from a direction along the spray direction of the liquid, and
• wherein the two or more conductors are electrically isolated from each other and are disposed to overlap with each other viewed from a direction along the spray direction of the liquid.
