PURPOSE:To enable a multi-head to be constituted by a simple structure by making positional precision between an electrostrictive vibrator and a cylindrical tube easy by a method wherein a plurality of cylindrical tubes are arranged at positions receiving pressure action of pressure generating parts formed by attaching an electrode to an electrostrictive vibrator or a magnetostrictive vibrator supported with a pedestal. CONSTITUTION:In order to assemble respective components, a number of glassy cylindrical tubes 5a composing a glass cylindrical tube line 5 are arranged in an adjacent state on a solid structured pedestal 10, and end faces on a front face side of respective cylindrical tubes 5a are so arranged as to be located on a same plane. An electrostrictive vibrator 2 is so arranged as to be put above the cylindrical tubes thus arranged uniform, and fixed lest an immoderate load should be applied. A gap among the vibrator 2, respective cylindrical tubes 5a composing the cylindrical tube line 5, and the pedestal 10 is filled by use of fillers being highly hard or the like around an ink chamber 7 so that the ink chamber 7 is hermetically sealed at that time. Since there is thus no necessity for strict registration of the electrostrictive or magnetostrictive vibrator to the cylindrical tube, assembling precision is not strictly requested and a manufacturing cost can be steeply reduced. |
