Abstract
A coating device includes a rotary head, a power supply part that applies a voltage to the rotary head, and a control part that controls the power supply part. The rotary head is configured so that a coating material is electrostatically atomized. The control part is configured so as to calculate a discharge current based on a total current flowing from the power supply part to the rotary head and a leak current, and control the power supply part based on the discharge current.
