ABSTRACT:
The liquid discharge head comprises: a plurality of ejection ports which eject liquid; a plurality of pressure chambers which communicate respectively with the plurality of ejection ports; a plurality of piezoelectric elements which deform the plurality of pressure chambers respectively and are provided on a side of the pressure chambers opposite to a side on which the ejection ports are formed; a common liquid chamber which supplies the liquid to the plurality of pressure chambers and is formed on a side of the piezoelectric element opposite to the pressure chambers; and a plurality of electric wires which stand upright from and substantially perpendicular to a surface on which the piezoelectric elements are mounted, the electric wires passing through a partition wall of the common liquid chamber and being electrically connected to the piezoelectric elements, the electric wires being formed by inserting wiring material for forming the electric wires into holes provided in the partition wall of the common liquid chamber.
