ABSTRACT:
An ink-jet printing head comprises at least one piezoelectric element block formed with a bore for storing ink and to which an electric voltage is supplied, and an ink supply member for supplying the ink to the bore of the piezoelectric element block. A droplet of ink is ejected from the bore with the aid of mechanical deformation of the piezoelectric element block produced when an electric voltage is supplied to the piezoelectric element block.
