PROBLEM TO BE SOLVED: To provide an inkjet type recording head unit capable of inexpensively achieving high-speed and high-quality printing, and its manufacture method and an inkjet type recording device. SOLUTION: The inkjet type recording head unit 1 provided with a plurality of nozzle trains 21A where nozzle apertures 21 ejecting ink are juxtaposed includes a pair of nozzle trains 21A ejecting the same color ink, wherein the pair of nozzle trains 21A having an inclination that the ink ejection amount of ink drops ejected from the nozzle apertures 21 based on the same driving signal becomes gradually smaller from one end side to the other end side of the nozzle train 21A is arranged so that the inclination that the ink ejection amount of the nozzle train 21A becomes gradually smaller may be reverse to each other.
