摘要:
The liquid ejection head comprises: a plurality of pressure chambers connected to a plurality of nozzles from which liquid is ejected, the pressure chambers being arranged in a two-dimensional configuration; a diaphragm which constitutes a wall of each of the pressure chambers, the wall being located opposite to the nozzles; a plurality of piezoelectric elements disposed at positions corresponding to the pressure chambers on a surface of the diaphragm which is on an opposite side of the diaphragm from the pressure chambers, the piezoelectric elements causing portions of the diaphragm corresponding to the pressure chambers to deform; an intermediate plate which is located on a piezoelectric element side of the diaphragm where the piezoelectric elements are disposed and which forms a space around a periphery of each of the piezoelectric elements; electrical wires for electrically connecting drive circuits which drives the piezoelectric elements with drive electrodes of the piezoelectric elements, the electrical wires being disposed in the intermediate plate; and an ink pool section which is located across the intermediate plate from the diaphragm and which supplies the liquid to the pressure chambers.
