PURPOSE:To reduce a driving voltage and contrive a marked reduction in the cost of a driving IC, by disposing a conductor part insulated from recording electrodes, between each adjacent pair of the recording electrodes. CONSTITUTION: A recording part 92 comprises recording electrodes 100, floating electrodes 101, a base 91, and an insulating film 96 provided on the recording electrodes. The base 91 is formed of a cuttable ceramic comprising mica as a main constituent, while the recording electrodes 100 and the floating electrodes 101 are formed from tungsten. The electrodes 100 are connected to a driving circuit through conductor wiring, and the electrodes 101 (each of which is disposed at an intermediate part between the recording electrodes) are electrically insulated from the recording electrodes 100. The electrodes 100 and 101 are covered by a coating material resistant to heat and relatively softer than the recording conductor, after the steps of adhesion to the base by an inorganic adhesive and patterning by etching with hydrofluoric acid. |
