An ink-jet head comprises a passage unit (10) including pressure chambers (36) each connected to a nozzle (35), and an actuator unit bonded (20) to the passage unit. The actuator unit includes active portions for changing volumes of the respective pressure chambers. Kinds of passage units different in positions of pressure chambers distant from a reference position set on a face of each passage unit, are prepared for a single kind of actuator units fabricated in the same design shape with a positional difference between corresponding pressure chambers in the different kinds of passage units increasing as a distance of the pressure chambers from the reference position increases. <IMAGE> |
