PURPOSE:To facilitate the manufacturing of the electrodes of a high-density printed electrode plate and to enable the lowering in the capacity between electrodes, by superposing two printed electrode plates wherein electrode leading end parts and wiring parts are collectively formed and using the cross-sections thereof as the terminal surfaces of recording electrodes and arranging electrodes in a zigzag pattern. CONSTITUTION:A printed electrode plate is constituted by forming electrode part patterns 32 and matrix wiring parts 33 to the front and back surfaces of a substrate 31 and providing protective cover coatings 34 to both outside surfaces t he substrate 31. As the material of the substrate 31 and the cover coatings 34, polyimide or a glass/epoxy resin for enhancing the hardness of each electrode is used. Copper or nickel is used in the electrode part patterns 32 and matrix wiring parts 33 to the front and back surfaces of a substrate 31 and providing protective cover coatings 34 to both outside surfaces of the substrate 31. As the material of the substrate 31 and the cover coatings 34, polyimide or a glass/epoxy resin for enhancing the hardness of each electrode is used. Copper or nickel is used in the electrode part patterns 32 and the matrix wiring parts 33 and an insulating resin is used as a filler material 35. Printed electrode plates 30a, 30b having the same constitution are superposed back to back and the pitch (p) between electrodes, the width (w) of each electrode and the thickness (h) of each electrode part pattern are made equal. These electrode part patterns are arranged in electrode arrangement in a zigzag pattern and superposed in constitution such that the pitches p' of the electrodes with adjacent electrodes become equal. |
