PROBLEM TO BE SOLVED: To improve a yield by selecting only good products of short units and assembling them and to achieve a low cost by making the shapes of respective units the same and thereby reducing a man-hour for selection during assembly when longitudinal inkjet recording heads are mass-produced. SOLUTION: An inkjet head comprises an actuator (a first substrate) 40 forming a piezoelectric element, a vibrating plate 30 transmitting an energy from the piezoelectric element to a liquid, a liquid room forming member (a second substrate) 20 connected to the vibrating plate 30 and forming a liquid flow path corresponding to an arranging site of the piezoelectric element, and a nozzle plate 10 communicating with the liquid flow path and on which a nozzle 11 for delivering liquid droplets is formed. In this inkjet head, the liquid room forming member 20 is formed by etching a <110> silicon, and is constituted by combining a plurality of flow path units 20a and 20b with the same pattern.
