LIQUID DISCHARGE HEAD, LIQUID DISCHARGE DEVICE, AND RECORDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To massproduce a recording system while a yield is improved by a method wherein a film component intercepting a gap formed between adjoining substrate units and a liquid channel is arranged between the substrate unit and a top plate. SOLUTION: A silicon substrate unit 402 wherein a plurality of energy generating elements 401 are patterned is arranged on a base plate 403. A film 404 covers a space between the silicon substrate units 402 arranged on the base plate 403. Those are elements of a first substrate. The film 404 has a comblike longitudinal one end part. A plurality of pieces 404a projected from this one end part is so formed as to be located on a gap 402a between adjoining silicon substrate units 402 when they come in top contact therewith. Further, a discharge opening 406 is formed to a top plate 405 provided wherein a second substrate having a recessed part for forming a channel and a discharge opening forming component are integrally formed by bonding according to the energy generating element 401.
