PROBLEM TO BE SOLVED: To provide a jet auxiliary anode that can realize speeding-up of surface treatment such as plating by inserting it in a basket-shaped barrel with an open upper face and directly supplying a metal ion and an electric current to an object to be plated. SOLUTION: In a tubular processing solution nozzle 3 made of an insulation material, there are provided a coil electrode 5 made of an insoluble metal and a rod electrode 6 made of a plating metal. The two electrodes 5, 6 are brought into contact with each other, with the rod electrode 6 of the plating metal installed either inside or outside the coil electrode 5 of the insoluble metal.
