ABSTRACT:
A liquid discharging head includes a channel unit formed of a plurality of stacked plates having openings and a liquid channel formed of the openings of the stacked plates. A curing material is filled in a step formed due to shift of the openings provided in the adjacent plates respectively, and the curing material forms part of an inner surface of the liquid channel. Consequently, the channel inner surface becomes smooth, and a liquid discharging head with little residual bubbles and with excellent bubble discharging capability is provided. Further, the attenuation of a pressure wave due to the step can be prevented.
