Summary:A frictional electrification gun for use in electrostatic painting which can electrostatically charge powder paint to a sufficient degree without the need of an elongated and twisted charging portion made up of nonconductive resin tubes. At the inlet of the charging portion made up of nonconductive resin tubes (10) is provided a pre-charging portion for dispersing and charging powder paint. It has a nonconductive resin ring (33) through which powder paint is fed swirling along its inner surface. The paint is thus sufficiently charged.
