Title: Apparatus for jetting ink utilizing lamb wave and method for manufacturing the same

Abstract: An apparatus for jetting ink utilizing a lamb wave and a method for producing the same, the apparatus including an ink chamber having nozzles, and an ejecting force source for supplying an ejecting force to eject the ink out of the nozzles. The ejecting force source includes inter-digital transducer electrodes for applying a voltage of a predetermined voltage, a piezoelectric element for generating the lamb wave by means of the voltage applied from the inter-digital transducer electrodes. Thus, as the voltage is applied to the inter-digital transducer electrodes, the lamb wave is generated from the lamb wave generating board, and the ink reserved in the ink chamber is ejected out of the nozzles.
