PROCESS FOR MANUFACTURING LIQUID EJECTION HEAD, AND LIQUID EJECTION HEAD

摘要

PROBLEM TO BE SOLVED: To enhance productivity remarkably by ensuring nozzle position with high accuracy even when a wide nozzle sheet is used thereby reducing failure rate, and to realize good ejection characteristics by a nozzle exhibiting high positional accuracy. SOLUTION: A sheet 17' for forming a nozzle ejecting ink in the form of a liquid drop is stuck to a head frame 16 and then a nozzle 18 is formed in the sheet 17' thus ensuring highly accurate positional relation between the nozzle 18 and a heating resistor for imparting energy to ink.
