摘要:
A liquid discharge head may include a flow channel unit having a plurality of pressure chambers. The head may be manufactured by manufacturing an actuator unit having a piezoelectric layer which covers the pressure chambers. The actuator unit may be manufactured by forming a first electrode and a second electrode thicker than the first electrode on the actuator unit, and forming a conductive layer laminated on the first electrode. The conductive layer may deform, and the sum of the thicknesses of the conductive layer and the first electrode may be larger than the thickness of the second electrode prior to the fixing step. The head may be manufactured by positioning the actuator unit on a cavity plate, and fixing the actuator unit to the cavity plate by heating and pressurizing. The conductive layer may be deformed by the pressurizing force more than the first and the second electrode.
