Abstract
A multi-nozzle ink jet head formed by semiconductor processes is disclosed. The multi-nozzle head has a nozzle plate (38) in which are formed a plurality of nozzles (39), an FPC (42) in which are formed a plurality of ink chambers (29), and energy generating layers (23, 26, 27), and wiring patterns (42A, 42B) for the energy generating layers are provided on the FPC (42), thus making connection to external circuitry easy.
