PROBLEM TO BE SOLVED: To sufficiently exhibit electrostatic coating effect even in the case of a low voltage as a spray gun for electrostatic coating which uses coating having a low resistance value. SOLUTION: The spray gun for the electrostatic coating enables the coating flowed out and aired from a coating jetting nozzle to be a ground potential and arranges an electrode outside a coating spray area. An atomized air jetting port is arranged at a coating jetting port and its surrounding as an atomizing means. A nozzle (LV nozzle) for allowing the coating and air to collide with each other with directional components where the direction of the jetting of the coating and the direction of the jetting of central air cross each other and spraying them is used. A taper surface where the coating jetting port is expandably opened is formed, and a plurality of V-shaped grooves are notched toward the center of the jetting port in the outer peripheral face of the jetting port placed in the central hole of a cap.
