In a liquid discharge head including a surface plate having a plurality of discharge ports and a liquid discharge body having a discharge portion, the discharge portion and an opening are alternately arranged on the liquid discharge body and the liquid discharge body includes a bonding unit formed by combining two piezoelectric material plates. Each piezoelectric material plate is provided with a plurality of grooves on a first surface and has a first electrode on one side wall surface and the bottom of the groove of the piezoelectric material plate, a second electrode on the other side wall surface, and a third electrode on a second surface. Each piezoelectric material plate is polarized in a direction connecting the first electrode and the second electrode, and also in a direction connecting the first electrode and the third electrode, and the two piezoelectric material plates are bonded so that the first surfaces face each other to form the bonding unit. |
