摘要:
A liquid discharge head includes a substrate having an energy generating element configured to generate energy required to discharge liquid, a discharge port configured to discharge the liquid and provided in an opposed relationship to the energy generating element, a wall member defining a chamber adapted to store the energy required to discharge liquid the energy being generated by the energy generating element, a discharge portion defining a fluid path connecting the chamber and the discharge port, a supply path facilitating supplying the liquid into the chamber, and a pair of hollow portions provided in the wall member, wherein the hollow portions oppose each other and sandwich at least the entire discharge port in a direction from the discharge port to the substrate, and the hollow portions are independent of the chamber.
