Abstract: An electrostatic painting apparatus includes a painting gun having at one end thereof a paint spray section, and a connection section detachably connectable to an external paint supply section for receiving a supply of paint from the supply section and supplying the received paint to a paint storage section that stores and supplies the supplied paint to the painting gun. The connection section is surrounded and protected by a peripheral wall, so that paint can pass by the other end of the painting gun without reaching the connection section. Consequently, the connection section can be prevented from being undesirably smeared with the paint.
