PURPOSE:To form an energizing head of high resolution with good reliability by forming any of warps and wefts of conductive fiber, the other of cloth of nonconductive fiber, bonding fixedly the cloth to an insulator which contains hexagonal crystal boron nitride of specific weight ratio, and utilizing the conductive fiber as energizing electrodes. CONSTITUTION:Cloth woven with conductive fiber 33 such as metal wires and nonconductive fiber 34 such as polyester is bonded fixed to an insulator 32. A current is flowed between the fiber 33 and discharge destructive paper 31, an aluminum deposited layer of the paper is destroyed, a black color layer is exposed, and a pattern in response to and electric signal is visualized. The insulator 32 contains 20-90wt. of hexagonal crystal boron nitride. Thus, high resolution recording is performed and an inexpensive writing head can be formed. |
