Abstract
A liquid discharge head includes a nozzle member. The nozzle member includes a nozzle, a deformable laminar member, and an electromechanical transducer. The nozzle discharges liquid. The deformable laminar member has an opening forming the nozzle. The electromechanical transducer is disposed around the opening. The nozzle member is warped with respect to a discharge-side plane of the nozzle member in a surrounding area of the nozzle when no voltage is applied to the electromechanical transducer.
