ABSTRACT:
A recording head having a nozzle plate which has a sufficient thickness not to be deformed by a pressure vibration, and which is provided with concave portions on the back side of the plate with remaining a thickness corresponding to the longitudinal length of a nozzle in which concave portions of the nozzle are disposed. The concave portions formed on the back of the nozzle plate are arranged independently for each nozzle to suppress the influence of the pressure applied to the other nozzles as much as possible by utilizing the buffer function of each of the concave portions.
