<p>A method of fabricating an ink jet print head jetting ink though a ink jet nozzle (31) by pressurizing ink supplied to a pressure chamber (34) from a ink supplying portion, comprises the steps of: (a) applying flowable resin on a surface of a piezoelectric member (21) polarized in a thickness direction; (b) forming a low rigidity member (22) having a rigidity less than that of said piezoelectric member by curing the resin; (c) grinding a surface of said low rigidity member (22); (d) forming a plurality of grooves (23) extending from the surface of the low rigidity member (22) to an inside of said piezoelectric member (21); (e) forming electrodes (28) on entire inner surface of said grooves (23); and (f) sticking a top plate (30) to the ground surface to close an opening of the grooves (23), thereby forming the plurality of pressure chambers (34) communicating with the ink supplying portion and the ink jet nozzle (31). In this method, even if resin is cured and contracted, since the low rigidity member (22) is formed by curing the resin at (b) process and the surface of the low rigidity member (22) is ground at (c) process, the proportion of the height of the low rigidity member (22) and the piezoelectric member (21) is equalized. Consequently, coefficient and stability are improved in the jetting characteristics of ink. <IMAGE></p> |
