Abstract
An ink-jet recording apparatus jetts an ink droplet from a free surface of an ink material by propagating a surface acoustic wave. The apparatus includes a substrate, a slant face formed on the substrate, The slant face contacts the ink material with a grade in use. A vibration generator for generating plural surface acoustic waves, is formed on the substrate away from the ink material in use, and the plural surface acoustic waves are propagated along with the substrate and changed into plural longitudinal waves having propagating directions in the ink material. The propagating directions will be concentrated at a certain portion within the ink material.
