Abstract:
A liquid discharge head includes a substrate and a flow path wall member provided on the substrate and having a wall defining a flow path connected to a discharge port for discharging liquid. The flow path wall member is provided with a cavity not connected to the flow path, when viewed in a direction from the discharge port toward the substrate, the cavity has a shape of a character, and the character corresponds to information regarding the liquid discharge head.
