The invention discloses an electric shock shield surface discharge method. A plurality of electrode sets are evenly arranged on the front face of a shield body. An electrode in each electrode set is connected with a pulse high-voltage bag in an electric appliance box. The part, between every two adjacent electrode sets, of the shield body is provided with a plurality of electric conduction bars for dividing the adjacent electrode sets. A back plate is arranged on the back face of the shield body, and the electric appliance box is arranged on the back plate. An electric shock button is arranged on the back plate and is in control connection with the electric appliance box. The electrode sets are controlled by the electric appliance box to conduct discharge, high-voltage arcs between the electrode sets are divided into a plurality of sections of arcs through the electric conduction bars, and a high-voltage arc net is generated on the surface of an electric shock shield. The electrode sets are arranged on the front face of the shield body of the shield, the multiple electric conduction bars not connected are arranged between the electrode sets, long arcs and short arcs are properly arranged, the scattered high-voltage arc net is generated through the high-voltage bag, and effective electric shock is conducted on a criminal suspect located at a certain distance. Under the situation that the self-defense strength of the shield is not changed, the high-voltage arc net is additionally arranged on the surface of the shield, the deterring and dispersing means is used for mastering the initiative of the action.
