Zusammenfassung:	An ink jet head is provided that can effectively suppress operational interferences among adjacent cavities, and is capable of ultra-high-density and high-speed printing. The ink jet head is equipped with a plurality of cavities each having a volume that is variable by a deformation operation of a piezoelectric element, wherein beam members are provided between inner walls that interpose the cavity.
