An ink-jet printhead including a substrate, in which an integrated circuit for a driving logic circuit to selectively drive the nozzle, and a logic circuit to input/output printing data to/from a fuse array, are formed. The printhead further includes an electrode which is used for wirings of the integrated circuit and the logic circuit and is patterned on the substrate, a plurality of heaters which are formed on the electrode and generate heat by current applied through the electrode from the integrated circuit, and a fuse array which includes a plurality of fuse members formed on the electrode on a same plane with the heater and selectively fused by current applied through the electrode from the logic circuit and stores printing data. The printhead further includes a cover member which is provided on the heater and the fuse array and in which an ink chamber and a nozzle are formed in a position corresponding to each of the heaters.
