A method of producing an ink jet head is disclosed. The ink jet head includes a substrate formed with an ink pool in one major surface thereof, a plurality of pressure chambers in the other major surface thereof, a plurality of feed holes respectively extending from the ink pool to the pressure chambers, and a plurality of through passageways respectively extending from the pressure chambers throughout the substrate. The methods includes the steps of etching single photosensitive glass ceramics substrate to thereby form the pressure chambers, feed holes and through passageways, and heating the substrate to transform photosensitive glass ceramics of the substrate to ceramics. A plurality of nozzles may also be formed in the substrate.
