摘要： A liquid jet head includes a flow path member having a supply port through which liquid is supplied and a discharge port through which the liquid is discharged, and a cover plate having a liquid supply chamber that communicates with the supply port and a liquid discharge chamber that communicates with the discharge port. An actuator substrate has a plurality of parallel channels that extend between the liquid supply chamber and the liquid discharge chamber and the channels communicate with respective nozzles formed in a nozzle plate. The flow path member, cover plate, actuator substrate and nozzle plate constitute a laminated structure. A communication path is provided in one or both of the cover plate and flow path member for bypassing the liquid from the liquid supply chamber to the liquid discharge chamber so that air bubbles trapped in the liquid can be effectively discharged to the outside.

摘要： Isolation between electrodes is ensured to enhance resistance to a liquid. A conductive film is provided to a surface of a piezoelectric substrate, and laser processing is performed in a groove extending direction on the conductive film between a first groove and a second groove provided to the piezoelectric substrate to thereby form a laser processing area where the conductive film is removed to the surface of the piezoelectric substrate between the first groove and the second groove. In forming the laser processing area, an irradiation operation with a laser is performed along a plurality of laser processing lines extending in the groove extending direction. Further, the irradiation operation with the laser is performed a plurality of times for each of the laser processing lines, and the irradiation operations with the laser performed along the same laser processing line of the plurality of laser processing lines are performed at a time interval from when ending a previous irradiation operation with the laser to when starting a subsequent irradiation operation with the laser.

摘要： According to an embodiment, a liquid ejecting head chip includes an actuator plate, a cover plate, a common electrode, and a connection wiring. In the actuator plate, a plurality of discharge channels and a plurality of non-discharge channels which extend in a Z-direction are alternately arranged at a distance in an X-direction. The cover plate is stacked on an AP-side-Y-direction inner side surface, so as to close the plurality of discharge channels and the plurality of non-discharge channels. The common electrode is formed on an inner surface of each of the discharge channels. The connection wiring is divided so as to be formed in at least 3 or more places in the X-direction on the cover plate, and the common electrode connects the connection wiring to the flexible substrate.
