Abstract

A cavity plate for an ink-jet printhead includes a base material and a chamber sheet. An ink channel array constituting ink chambers is provided through the chamber sheet by a wire electric discharge machine, while an ink reservoir is formed on the base material by a wire electric discharge machine. Then, the chamber sheet and the base material are bonded to one another. Nozzles to eject ink may be created on a nozzle sheet, which is later connected to the chamber sheet. Alternatively, the nozzles may be directly provided on the chamber sheet. Thus, the cavity plate is provided having the ink chambers and the ink reservoir with high precision, without the increase in the production cost.
