<p>PROBLEM TO BE SOLVED: To provide a liquid jet head 1 having a structure which is easily processed and assembled.SOLUTION: A liquid jet head 1 comprises: a piezoelectric plate 2 in which a discharge groove 7 discharging liquid and a dummy groove 8 discharging no liquid are alternatively arrayed in a reference direction K; a liquid supply plate 3 which includes a liquid supply hole 3a supplying the discharge groove 7 with the liquid and is connected with one surface OS of the piezoelectric plate 2; a liquid discharge plate 4 which includes a liquid discharge hole 4a discharging the liquid from the discharge groove 7 and is connected with the other surface TS of the piezoelectric plate 2; and a nozzle plate 5 which includes a plurality of nozzles 9 communicated with the discharge groove 7 and is connected with a side face SS of the piezoelectric plate 2. The discharge groove 7 includes a going discharge groove 7a flowing the liquid to the direction of the nozzle 9 and a coming discharge groove 7b adjacent to the going discharge groove 7a in the reference direction K flowing the liquid from the direction of the nozzle 9. The going discharge groove 7a and the coming discharge groove 7b are communicated with each other in the vicinity of the nozzle 9, the liquid supply hole 3a is communicated with the going discharge groove 7a, and the liquid discharge hole 4a is communicated with the coming discharge groove 7b.</p> |
