发明名称 Liquid ejecting head and liquid ejecting apparatus
摘要 A liquid ejecting head includes a passage-forming substrate, a plurality of pressure-generating elements, and an IC chip. The passage-forming substrate has a nozzle opening, and a pressure-generating chamber communicating with the nozzle opening. The plurality of pressure-generating elements are provided on a surface of the passage-forming substrate with a diaphragm interposed therebetween. The pressure-generating elements have electrodes and cause pressure change in the pressure-generating chamber. The IC chip is mounted on the surface of the passage-forming substrate with the pressure-generating elements. In this liquid ejecting head, the electrodes of the pressure-generating elements include individual electrodes, and at least the individual electrodes are electrically connected to the driver circuit via the through electrode.
