Abstract:
A liquid discharge head includes a nozzle that discharges liquid droplets, a common liquid chamber that supplies liquid to an individual liquid chamber that is in communication with the nozzle, and a filter plate that is arranged in a liquid flow path of the common liquid chamber. The filter plate includes a filter part that filters the liquid and a damper part that reduces a pressure variation in the common liquid chamber, and the filter part is arranged to be thicker than the damper part.
