A method for manufacturing an ink jet head having a discharge opening for discharging ink and an ink passage communicated with the discharge opening, includes the step of forming the discharge opening by performing a cutting operation along a portion where the discharge opening is to be formed, while maintaining the ink passage in a pressurized condition by filling the ink passage with fluid. Another method includes the step of cleaning an ink passage by introducing liquid and gas into the ink passage alternately; and an ink jet apparatus comprising such an ink jet head, and a member for holding the ink jet head.
A method for manufacturing an ink jet head including a process for forming a plurality of discharge openings by cutting a plate-like construction comprising a substrate on which a plurality of energy generating elements for generating energy for discharging an ink are formed, an ink path for discharging the ink corresponding to said energy generating elements on said substrate, a liquid chamber communicating with said ink path, and a member having an ink supply port for supplying the ink into said liquid chamber, said cutting taking place at a position where said discharge openings for discharging the ink are to be formed,
