Liquid discharge head

摘要

A liquid discharge recording head comprising a substrate (2) provided with an energy generating element (1) for generating liquid discharging energy used for discharging liquid; and an orifice plate member (5) located on said substrate and provided with a discharge port for discharging liquid, wherein a flow path (8) communicated with said discharge port is formed between said substrate and said orifice plate member, wherein said orifice plate member surrounds said flow path and has a groove (9) in contact with said substrate, and a thickness of a peripheral portion of said orifice plate member is smaller than a thickness of the orifice plate member inside of said groove.
