PURPOSE:To easily prepare an electrode head capable of performing high quality printing through the stable printing of a clean dot with high density and with high accuracy, by respectively laminating at least two or more electrode needles from among a large number of the electrode needles, which are formed in a stripe form at a predetermined pitch by processing a metal plate, to form a recording electrode. CONSTITUTION:An insulating material 2 is processed in a micron order using a dicing apparatus for processing a semiconductive layer to form grooves 4 thereon. Next, etching processing is applied to the insulating material 2 so as to leave a frame 5 in order to hold electrode needles 1a in the manner to arrange the same at a predetermined pitch without generating irregular arrangement. Subsequently, the electrode needles 1a and electrode needles 1b are laminated in two stages to be embedded in the grooves 4 formed on the insulating material 2. Three or more electrode needles may be laminated. Next, a plate-shaped insulating material 2 is allowed to cover the grooves 4 having the electrodes 1a, 1b embedded therein and the insulating materials 2 are mutually adhered to fix the electrode needles 1a, 1b in the insulating materials 2 and, at last, the electrode needles are connected to lead wires 3, and the excessive parts of the electrode needles protruding from the insulating materials and the frame are cut off to perform molding. |
