Electrically conductive coating for cover of industrial robot
 An industrial robot for use in TIG arc welding or the like includes plastic covers for motors or the like. The plastic covers having an electrically conductive coating, and thus have an electrically conductive property, and are connected to a robot body, to thereby obtain a shielding effect similar to that of iron plate covers or the like.
