Abstract
In a method of manufacturing an ink-jet printer which uses a thin film sheet having adhesive layers respectively formed on the top and bottom sides, as an orifice plate, orifices are formed in the ink-ejecting side of the thin film sheet after the adhesive layer on that ink-ejecting side has been removed. This prevents the formation of the orifices from being adversely affected by any otherwise residual of the adhesive layer and can thus permit accurate formation of orifices of a desired shape. Even if helicon-wave dry etching which ensure fast etching using high-power energy is used to form orifices, therefore, no adhesive layer is thermally expanded to be a residual so that multiple orifices can be formed simultaneously and quickly.
