ABSTRACT:
A jetting element has a plurality of nozzles, a heating body for jetting ink droplets from the nozzles, and an ink chamber communicating with the nozzles. A manifold is bonded with the jetting element through an adhesive, and has an ink flow path formed therein to supply an ink to the jetting element. After the ink has been charged, the interior of the ink flow path is held at a negative pressure. An adhesive whose gas permeability is smaller than 2.0.times.10.sup.-6 cm.sup.3 .multidot.cm/cm.sup.2 .multidot.sec.multidot.atm and whose angle of contact with respect to the ink is 45.degree. or less is used as the adhesive. The bonded portion created by the adhesive has a smooth shape so that air bubbles are hard to adhere to the bonded portion.
