Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electrostatic coating device capable of remarkably decreasing the sticking of a coating material on the boundary between a mask member and a material to be coated and the outside surface of the mask member, and an electrostatic coating method capable of easily coating a zone to be coated. SOLUTION: The insulating mask member 27, in which a copper plate 26 is involved, is arranged on an uncoated surface 20b of a metallic plate 20 having a potential made zero through an earth plate 21 to electrify the copper plate 26 so as to be negative. The coating material particles 22 electrified to be negative with an electrostatic coating gun 11 is sprayed from the electrostatic coating gun 11 electrified to be negative, which is imparted with negative high voltage in a high voltage generator 13, to an electrostatic field formed by the metallic plate 20, the mask member 24 and the electrostatic coating gun 11.
