PURPOSE: To make it possible to attain miniaturization and wt. reduction and to enhance integration and durability, by forming all of a nozzle plate, an ink flow passage plate, an insulating plate, a bimorph type PVdF plate and a flexible printed circuit board from a thin film and laminating, adhering and forming all of them in the above mentioned order.
CONSTITUTION: A head is constituted to a nozzle plate film 1, an ink flow passage film 2, an electric insulating film 3 and a bimorph type PVdF film 4 while aluminum electrodes 5 are printed on a drive part. A conductive pattern 8 is printed on a flexible printed circuit board film 6 in order to transmit a drive signal to the aluminum electrode 6 of the PVdF film 4. The film laminated head is thin and, as the material quality thereof, polyester or nylon is used in order to satisfy adhesiveness, flexibility and toughness. Because the head is integrally held and provided with rigidity as mentioned above, miniaturization, et. reduction and the enhancement of integration are attained by integrating the head, ink supply system and the electric signal system and durability is enhanced.
