Method of manufacturing an ink ejecting device wherein electrodes formed within non-ejecting channels are divided and electrodes formed within ejecting channels are continuous

摘要

A method of manufacturing a substrate of an ink ejecting device in which an electrode formed at the bottom surface of an air chamber is removed with a diamond disk, without erroneously removing an electrode formed at an actuator forming the internal surface of the air chamber, by forming the air chamber with a width not smaller than that of an ink channel. The diamond disk for removing the bottom surface of the electrode of the air chamber may be the same as or have the same dimensions (width) as the ink channel.
