摘要： A liquid ejecting head includes a flow path formation substrate on which individual flow paths communicating with nozzle openings for ejecting liquid are provided, a first member which is provided at one surface side of the flow path formation substrate and has pressure generation units for generating pressure change in liquid in the individual flow paths, and a second member which is provided at a surface side of the flow path formation substrate, which is opposite to the first member. Dummy flow paths are provided on the flow path formation substrate independently of the individual flow paths. Exposure portions which expose a part of wall surfaces of the flow path formation substrate which form the dummy flow paths, are provided at least one of the first member and the second member.

摘要： A charge accumulated on an insulative nozzle plate flows into the ink with which nozzle openings and pressure generation chambers are filled and reaches a vibration plate. The charge that has reached the vibration plate is driven out therethrough because the vibration plate is made of a conductive ceramic material and is grounded. Therefore, it is possible to obtain an ink jet recording head in which insulation breakdown of the vibration plate caused by the charge accumulated on the vibration plate is suppressed from occurring and a driving circuit is suppressed from being damaged.

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.

摘要： One of the two flow passages branches from one of two ink cartridges to one of the two discharging portions and one of the two individual discharging portions. The other flow passage branches from the other ink cartridge to the other discharging portion and the other individual discharging portion. A ratio of frequency of use of each of the discharging portions, Ra, and frequency of use of each of the individual discharging portions, Rb, satisfies Ra:Rb=1:½.
