More Information
Summary:A liquid discharge head includes an individual liquid chamber having a nozzle through which a liquid is discharged in a liquid discharge direction, a piezoelectric element facing the individual liquid chamber, a first groove adjacent to the piezoelectric element in a nozzle array direction, a dummy individual liquid chamber without any nozzle, a dummy piezoelectric element facing the dummy individual liquid chamber, and a second groove adjacent to the dummy piezoelectric element in the nozzle array direction. The first groove extends in the liquid discharge direction. The second groove has a shorter length in the liquid discharge direction than the first groove.
