摘要
An electrostatic coating device comprising a nozzle section that discharges a liquid to a substrate, a counter electrode that is disposed in such a way as to face the nozzle section and supports the substrate and a power source device that applies a voltage between the nozzle section and the counter electrode further comprises an instantaneous stop circuit that selectively grounds the nozzle section. When the nozzle section is grounded by the instantaneous stop circuit, a charge remaining in the nozzle section goes to the ground and the charge remaining in the nozzle section disappears. For this reason, after the power source device is turned off, dripping of the liquid from the nozzle section can be completed as quickly as possible.
