摘要:
The liquid ejection head includes: a plate which has a plurality of ejection ports which eject a liquid; a plurality of pressure chambers connected respectively to the ejection ports; a plurality of piezoelectric elements which respectively deform the pressure chambers, the piezoelectric elements being provided on a side of the pressure chambers opposite to a side on which the ejection ports are formed; a common liquid chamber which respectively supplies the liquid to the pressure chambers, the common liquid chamber being provided on the side of the pressure chambers opposite to the side on which the ejection ports are formed; and a plurality of wiring members which transfer a drive signal to the piezoelectric elements, the drive signal driving the piezoelectric elements for deforming the pressure chambers, wherein: the wiring members are formed so that at least a portion of each of the wiring members rises upward through the common liquid chamber in a substantially perpendicular direction with respect to a surface on which the piezoelectric elements are disposed; and the wiring members are connected to the piezoelectric elements by means of an adhesive comprising a plurality of conductive particles and a non-conductive resin.
