<p>PURPOSE:To facilitate manufacture and to reduce costs by printing floating electrodes in heat-resisting conductive ink through silk and thus forming the electrodes on an insulating layer. CONSTITUTION:On a surface of an insulating base board 18, plural X conductors 19 and plural Y conductors 20 are arranged. On a reverse surface covering the conductors 19 and 20 on the base board 18, a heat-resisting insulating film 26 is laminated in the 1st heat-resisting insulating layer. On a surface of this film 26, plural floating electrodes 27 are formed each covering at least one of the conductors 19 and 20 by being printed in heat-resisting conductive ink through silk. Further, a heat-resisting insulating film is laminated on the reverse surface covering those plural electrodes 27 to form the 2nd heat-insulating layer. On the layer, a character sheet 30 is placed to constitute a tablet 31. Consequently, the tablet is manufactured without using a large-sized device for a multilayered printed board, and the stage of laminating tablets is unnecessary.</p> |
