An ink-jet head having a plurality of nozzles for spraying ink fed by an ink supply comprises a main body, which includes a plurality of compartments (112) provided for each nozzle and charged with ink and a plurality of pressurizing parts for applying pressure to the compartments (112) to make the compartments (112) to spray ink from the nozzles. An individual electrode (109) is provided to drive each pressurizing part. The pressurizing parts each have at least one contact (121) connected with an external source of a signal for controlling the pressurizing part. Thin-film wiring patterns (123) for connecting the individual electrodes (109) and the contacts (121) are formed to facilitate connections with the external source and increase productivity and reliability.
