PURPOSE:To obtain easily a multi-needle recording electrode having aligned auxiliary electrode face and excellent performance by a method in which a comb-shaped auxiliary electrode base material is formed of a plating-affinitive resin, and the base material is held by a virtually unplatable resin and provided with a metal plating. CONSTITUTION:A virtually unplatable resin 2 is packed around an auxiliary electrode base material 1 molded of an easy platable resin to obtain an auxiliary electrode body 8. Then, the surface of the base material 1 is treated, provided with an electroless resin plating layer 3, and then provided with an electric plating layer. Then, recording electrode wires aligned in a straight line are set at the center, the auxiliary electrode body 8 with plating layer is arranged on both sides of the recording electrode wires and fixed with an adhesive, the integral portion 5 of the auxiliary electrode is cut off to divide it into each auxiliary electrode, and then lead wires 7 are soldered to each. |
