PROBLEM TO BE SOLVED: To provide a liquid discharge head comprising a unit laminate body that has durability to discharge high-viscosity ink, is arranged in high density, and has ink discharging sections formed for reducing crosstalk.SOLUTION: The liquid discharge head comprises: a surface plate (a nozzle plate 8) including a plurality of discharge openings 7; a recording-liquid discharge body (an ink discharge block 5) including a plurality of pressure chambers 3; a plurality of openings 4 formed overlapping with the plurality of pressure chambers 3; and a plurality of pressure-chamber separation grooves 15 arranged between the plurality of pressure chambers 3. The recording-liquid discharge body is formed by laminating alternately first piezoelectric material plates 1 with second piezoelectric material plates 2. The pressure chambers 3 and the openings 4 are formed alternately in a direction of the laminate. The pressure-chamber separation grooves 15 are formed so that the plurality of first piezoelectric material plates 1 and the plurality of second piezoelectric material plates 2, laminated, penetrate in the direction of the laminate. |
