Abstract

A high voltage generation device (9) includes: a voltage boosting portion (22) that boosts a voltage and that includes high voltage output terminals (22g, 22h); and a resistance portion (37) that includes an input terminal (37a), a ground terminal (37c), a resistance body (38) that connects the input terminal (37a) and the ground terminal (37c), and a contact portion (39) or a variable contact portion (48) that forms a contact in an intermediate position of the resistance body (38) between the input terminal (37a) and the ground terminal (37c). The high voltage output terminal (22g) is connected to a coating gun (3), the high voltage output terminal (22h) is connected to the input terminal (37a) of the resistance portion (37), and an output terminal (37b) of the resistance portion (37) or the variable contact portion (48) is connected to a robot arm (4).
