Abstract
A liquid discharge apparatus has liquid chambers and nozzles that discharge droplets of liquids contained in the liquid chambers through liquid channels. The liquid discharge apparatus includes a substrate provided with partitions on one face thereof, the liquid chambers and the liquid channels being defined between the partitions. The liquid discharge apparatus further includes a nozzle sheet provided with adhesion-improving layers at least at positions corresponding to the top faces of the partitions and the nozzles for discharging liquid, the nozzle sheet and the top faces of the respective partitions being bonded to each other with the adhesion-improving layers. The liquid discharge apparatus also includes driving elements provided on the face of the substrate at positions corresponding to the liquid chambers, for changing the pressure of the liquid chambers. The liquid discharge apparatus is used as a printer head for ink jet printing.
