Patent ID: 8622523

Claim:
A liquid discharge head having a substrate in which a supply port for supplying a liquid is formed and a member for forming on a surface of the substrate a liquid storing region in which liquid is stored, the liquid storing region being closer to a region of a discharge port for discharging the liquid than the supply port and communicating the discharge port with the supply port, wherein the liquid storing region includes a region at a side of the substrate and a region at a side of the discharge port, and an area of a cross-section of the region at the side of the substrate parallel to the surface of the substrate is larger than an area of a cross-section of the region at the side of the discharge port parallel to the surface of the substrate, and wherein the region at the side of the substrate and the region at the side of the discharge port are communicated with each other through a plurality of flow path portions which are partitioned.
