Abstract
In a thermal head, individual electrodes, a common electrode and a heating body are formed on an insulated base plate, and an insulating protective film is formed on the heating body. A conductive protective film is mounted on the insulating protective film to laminate on and connect with the common electrode. The conductive protective film has a thermal conductivity higher than that of the insulating protective film. Since the conductive protective film is connected to the common electrode, effects by static electricity due to friction with thermal-sensitive paper are prevented.
