Abstract: PROBLEM TO BE SOLVED: To enhance productivity remarkably by sticking even a thin and wide nozzle sheet produced through electrocast easily and accurately, and to realize good ejection characteristics by a nozzle sheet ensuring flatness.
SOLUTION: A nozzle sheet 17 having a nozzle formed on a mother die 30 is produced by electrocast using the mother die 30 and then stuck to a head frame 16 along with the mother die 30. Subsequently, the mother die 30 is released from the nozzle sheet 17 thus ensuring highly accurate positional relation between the nozzle and a heating resistor for imparting energy to ink.
