An ink-jet head jets ink by applying energy of surface acoustic waves to the ink for recording on a recording medium. The ink-jet head includes a surface acoustic wave propagation element that propagates surface acoustic waves, a plurality of surface acoustic wave generation devices disposed on the surface acoustic wave propagation element, a plurality of ink ejection sections that are disposed in the surface acoustic wave propagation element and disposed alternately with the plurality of surface acoustic wave generation devices along a single line, a plurality of surface acoustic wave amplification devices located between the surface acoustic wave generation devices and the ink ejection sections on the single line, and an ink supply unit that supplies ink to the ink ejection sections.
