スパーク防止装置。[Scope of Utility Model Registration Claim] When the increasing slope of the load current flowing through a circuit including a high-voltage power supply, the coating machine, and the object to be coated is compared with a reference value, and the increasing slope of the load current exceeds a certain value, In a spark prevention device for an electrostatic coating device that detects this as a sign of spark and generates a detection signal to perform a spark prevention operation, the high voltage application section of the paint sprayer includes a high voltage application section and a spark prevention device. A conductor having a corona discharge ability in which the discharge current increases earlier than the high voltage application part when the object to be coated approaches is attached via a current limiting resistor, and the current limiting resistor is configured to prevent the discharge from the conductor from increasing. A spark prevention device for an electrostatic coating device, characterized by having a resistance value capable of suppressing the discharge current so as not to cause sparks.
