The head structure comprises a piezoelectric substrate 1 of, for example, quartz, Rochelle salt, BaTiO(3) or similar material. Substrate 1 is cut in the direction of its crystal axes in such a manner that a voltage applied to electrodes 4, 5, arranged on opposite side faces 2, 3, causes a striction of substrate 1 between electrodes 4, 5.
