Abstract: PROBLEM TO BE SOLVED: To prevent the ink ejection characteristics from lowering by ensuring a correct nozzle pitch at the joint when a line ink jet head is manufactured by connecting a plurality of ink jet heads, to increase the yield of a line head having an extremely large number of nozzles and to ensure fluidity in a manufacturing system for small diameter wafer while reducing the manufacturing cost and facility investment. SOLUTION: Since channels and cover glass chips can be arranged on a linear glass substrate on which wiring is formed and connected, nozzle pitch at the joint of head is equal to that between other nozzles. Consequently, print is not disturbed at the connecting part resulting in high resolution print.
