PURPOSE:To prevent the damage of the electrodes of electrostrictive strain vibrators and the fluctuation of the cast position and direction thereof and to maintain the resolution of a regenerated image by molding a plurality of cylindrical electrostrictive strain vibrators of the multiple ink-jet head in synthetic resin. CONSTITUTION:A plurality of cylindrical electrostrictive strain vibrators 1 are inserted into a plurality of holds 8a of one supporting plate 8 respectively and are fitted in parallel to each other, and then are put in a mold. Next, the synthetic resin 5 melted is poured into the mold and fixed. In this way, the cylindrical electrostrictive strain vibrators 1 in plural and one supporting plate 8 are molded in the synthetic resin 5. |
