Abstract: There are provided driving electrodes ( 25 ) on walls ( 24 ) separating both sides of individual ink chambers ( 22 ) formed in the form of an array of multiple grooves. External circuit connecting electrodes ( 11 ) for connecting these driving electrodes ( 25 ) to an external circuit are formed on exposed surface regions of electrically conductive material ( 10 ) filled in the individual ink chambers ( 22 ) at a rear end portion of a head. Each of the aforesaid exposed surface regions has an area larger than the cross-sectional area of each ink chamber as measured along a direction perpendicular to the ink chamber array.

Abstract: Driving electrodes (25) are arranged at partition walls (24) partitioning both sides of each of ink chambers (24) formed in rows of grooves. Electrodes (11) for connecting the driving electrodes (25) to an outside circuit are formed on surfaces, exposed at the rear end portions of a head, of an electrically conductive material (10) filled in the ink chambers (22). Each exposed surface has an area larger than that of a cross section of each ink chamber taken perpendicularly to the length direction of the ink chamber.

Abstract: PROBLEM TO BE SOLVED: To bond a nozzle plate to an inkjet head by an easy method ensuring bonding strength and adhesion strength. SOLUTION: In the method for bonding a nozzle plate 1 having an ink ejection hole 4 to a head part 2 for imparting energy to ink in order to eject ink at the time of manufacturing an ink ejector, a sheet adhesive 6 is pressed against the nozzle plate adhesive plane at the head part 2, the nozzle plate adhesive plane and the sheet adhesive 6 are heated, a separator is separated from the sheet adhesive 6 to transfer the adhesive to the nozzle plate adhesive plane, and then the nozzle plate 1 is bonded to the nozzle plate adhesive plane by pressing.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid drop jet apparatus which is easy to manufacture, has a superior productivity and can be made compact. SOLUTION: In the liquid drop jet apparatus, a conductive member 26 is set to one end of a groove formed to a piezoelectric member 27, and the groove is covered with a cover plate 3. Ink supplied into an ink channel 12 is jetted by changing the volume of the ink channel 12 formed in the groove. An ink supply port 68 for supplying ink is set to the side of the end where the conductive member 26 is set.
