ABSTRACT:
A method for making a liquid ejection head includes the steps of placing a vibrator unit including a plurality of piezoelectric elements arranged in a comb shape in a head housing; filling each of the spaces between the piezoelectric elements and in the receiving sections of the head housing, and the liquid feed openings with a resin; depositing a resin on a planar surface including the ends of the piezoelectric elements, followed by patterning the resin to form islands which are isolated pressure-transmitting portions; placing a diaphragm on the patterned resin and forming a soluble resin pattern on the diaphragm; forming a coating layer on the soluble resin pattern; and dissolving away the soluble resin pattern to form a liquid feed chamber, pressure chambers, etc.
