摘要：
A nozzle plate made of conductive ceramics is grounded. Therefore, electric charges do not easily accumulate on the nozzle plate. The migration of electric charges from nozzle orifices to a diaphragm plate through ink filled in pressure generation chambers is unlikely to occur or significantly less likely to occur. Thus, it is possible to prevent the dielectric breakdown of the diaphragm plate caused conventionally by accumulated electric charges and to provide an ink-jet recording head that is substantially free from the damage of a driving circuit.
