PROBLEM TO BE SOLVED: To provide an inkjet printer head which can make the whole apparatus compact while it easily meets color recording by making ink to be discharged multicolor, and which can use parts of a conventional inkjet printer head as common parts. SOLUTION: A plurality of pressure chambers 22 are set by the same arrangement spacing as that of nozzles along an array direction of the nozzles 19. A small manifold chamber 21 is divided to a plurality of chambers by partition walls 27 in the array direction of the nozzles 19. The plurality of chambers are arranged corresponding to every suitable number of the pressure chambers 22. Each of ink circulation ways 23 is equipped with an inlet part 23a connected to the small manifold chamber 21 and an outlet part 23b connected to the pressure chamber 22. The outlet parts 23b are set by the same arrangement spacing as that of the pressure chambers 22 in the array direction of the nozzles 19. The inlet parts 23a are set by an arrangement spacing wider than that of the outlet parts 23b side in the vicinity of at least the partition walls 27 in the array direction of the nozzles 19 to avoid the partition walls 27.
