PROBLEM TO BE SOLVED: To reduce variation in discharge speed of ink from nozzles between liquid discharge devices and the like. ! SOLUTION: For manufacturing an inkjet head, a laminate 55 of piezoelectric layers 42, 43 and a common electrode 44 is manufactured, and in parallel with this, a laminate 56 of a channel unit 21 and an ink separation layer 41 is manufactured. Next, the laminate 55 and the laminate 56 are bonded by a thermosetting adhesive 50. Then, an individual electrode 45 is formed on an upper surface of the piezoelectric layer 43 at a part overlapping with a pressure chamber 10. At this time, the individual electrode 45 is formed on the upper surface of the piezoelectric layer 43 at a part shifted from a part overlapping with a central part of the pressure chamber 10 by a shift amount E depending on a contraction amount D of the piezoelectric layers 42, 43 after bonding of the laminate 55 and the laminate 56 with respect to those of before the bonding. !
