1. An electrostatic painting method comprising steps of:
attaching a grounded clip to an insulating object to be painted;
spraying, by a paint gun, water-based paint to the clip to start electrostatic painting;
spraying the water-based paint to the object to be painted while moving the paint gun from a position where the painting has started in a predetermined direction to form a first band-like painting film;
spraying the water-based paint to the object to be painted while moving the paint gun to thereby form a second band-like painting film, the second band-like painting film being formed in parallel to the first painting film, and a part of the second band-like painting film overlapping the first painting film, wherein
an amount of overlap between the first and second painting films is within a range in which the first and second painting films overlap each other by greater than or equal to ½ of the widths of the first and second painting films.
