PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid droplet ejection head capable of securing positional accuracy of piezoelectric vibrator rows corresponding to two adjacent nozzle rows. SOLUTION: Piezoelectric material plates 40 made by laminating piezoelectric material and conductive material alternately and configured such that both ends in a displacing direction are inactive areas and other part is an active area are fixed on two parallel surfaces of a fixed substrate 20 on the inactive area at one end so as to make the active area project from the fixed substrate 20, and long notches 34 are formed in a projecting direction from the fixed substrate 20 at predetermined intervals on the piezoelectric material plates 40 simultaneously, so as to manufacture a vibrator unit in which a piezoelectric vibrator 14 is formed between the notches 34, and the vibrator unit is housed in a head case. The notches 34 formed on the two piezoelectric material plates 40 are shifted by half of the predetermined interval each other, whereby the piezoelectric vibrators 14 are set to two-line staggered arrangement.
