Abstract: An electrostatic coating apparatus includes: a spray gun configured to spray a coating material onto a coating object; a voltage application device configured to apply a high voltage to the spray gun; and a current measurement device configured to measure electric current flowing through the spray gun. When the spray gun, which is in a state of not spraying the coating material onto the coating object and is under application of the high voltage from the voltage application device, is located at a distance from the coating object, the electric current flowing through the spray gun is measured by the current measurement device. A grounded state of the coating object is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.

Abstract: An electrostatic painting method includes supplying, via a pure water supply passage, pure water to a paint tank within which paint is stored, applying a voltage to paint that is pushed out from the paint tank by the supplied pure water, and spraying the paint to which the voltage has been applied, at an object to be painted. Pure water remaining in the pure water supply passage is replaced to increase an electrical resistance value of the pure water before starting to paint the object to be painted.
