摘要 |
A liquid discharge head includes a substrate having a discharge port, a plurality of energy generating elements disposed on a first surface of the substrate for generating energy to discharge liquid from the discharge port, a liquid supply port, and a member provided on the first surface and forming a wall of a liquid chamber and a wall of a liquid path from the liquid supply port through the liquid chamber to the discharge port. A plurality of first penetrating electrodes penetrate the substrate from the first surface to the second surface, wherein one of the first penetrating electrodes electrically connects one of the energy generating elements, and a plurality of second penetrating electrodes penetrate the substrate from the first surface to the second surface, wherein one of the second penetrating electrodes electrically connects to the same energy generating element connected to the first penetrating electrode. Also, first and second power wirings are provided, and a plurality of driving elements are electrically connected between the first penetrating electrode and the first power wiring, correspondingly to each of the energy generating elements, to drive and control the energy generating elements.
