PROBLEM TO BE SOLVED: To provide a torch nozzle and a contact tip coated with a film which effectively prevents a sputter sticking, shows an excellent tight adhesion to a base material, and is formed by a simple method, to provide a torch nozzle and a contact tip from which a stuck sputter is easily removed, and further to provide a torch nozzle and a contact tip with which an operator's burden is decreased. SOLUTION: The torch nozzle for welding and the contact tip are characterized by the fact that they are coated with a heat-resistant resin in which particles having a low friction are dispersed, or the torch nozzle for welding and the contact tip are characterized by the fact that they are coated with a heat-resistant resin in which non-adhesive particles are dispersed, and preferably, the torch nozzle for welding and the contact tip are characterized by the fact that they are coated with a fluorine resin in addition to and covering over the heat-resistant resin, and more preferably, the torch nozzle for welding and the contact tip are formed by a magnesium alloy.
