发明名称 Liquid ejection head, image forming apparatus and method of manufacturing liquid ejection head
摘要 A liquid ejection head having a plurality of ejection ports which eject liquid, a plurality of pressure chambers which are connected respectively to the ejection ports, a plurality of piezoelectric elements which are disposed on a side of the pressure chambers reverse to a side adjacent to the ejection ports and respectively deform the pressure chambers, and a laminated body which is disposed on the side of the pressure chambers reverse to the side adjacent to the ejection ports and includes a plurality of ceramic thin plates arranged to overlap each other. The laminated body is formed with a common liquid chamber which supplies the liquid to the pressure chambers, and electrical wires which supply drive signals to the piezoelectric elements and are formed so as to rise upward in a direction substantially perpendicular to a surface on which the piezoelectric elements are disposed.
