Abstract
The method of manufacturing a liquid ejection head includes the steps of: forming piezoelectric elements on a diaphragm; stacking an intermediate plate which includes recess sections for covering the piezoelectric elements and drive wires connected to the piezoelectric elements, on the diaphragm; connecting an integrated circuit to the drive wires; forming an actuator function unit by electrically and mechanically bonding the diaphragm, the piezoelectric elements, the drive wires, the intermediate plate and the integrated circuit, in such a manner that the piezoelectric elements are electrically driven via the integrated circuit; measuring displacement of the diaphragm by operating the integrated circuit; and bonding a flow path forming member to the actuator function unit after the step of measuring the displacement of the diaphragm, the flow path forming member being provided for forming pressure chambers connected to nozzles and forming a common liquid chamber for storing liquid supplied to the pressure chambers.
