Abstract

PURPOSE:To reduce the number of manufacturing processes by a method in which auxiliary electrodes are set on both sides of a recording electrode wire group, the integrated parts of the base are positioned and joined, and the recording face is cut into each auxiliary electrode. CONSTITUTION:An auxiliary electrode base 12 is made up by a method in which slits 14 are formed in a metal angle material 13, the flat plate part 13a on one side is separated and lead wires 16 are connected to auxiliary electrode parts 15. The electrode base 12 is held by an insulating spacer 18 and a pusher 19 for positioning in such a way that electrode parts 15 are buried and the integrated parts 13b is projected. Then, the electrode base 12 is molded with a resin 17' to form an auxiliary electrode body 17. The auxiliary electrode bodies 17 are positioned and connected with both sides of recording electrode wire group 21 at its integrated parts 13b, the integrated part 13b is cut off at the plane B-B' to form a recording face 22 where auxiliary electrode parts 13a are individually separated, whereby obtaining a multi-needle electrode 11. Thus, the needs for recasting the portions deprived of integrated portions can be eliminated and the number of manufacturing processes can thus be reduced.
