<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid discharge unit that can prevent an exuding part, formed as an adhesive exudes to a surface of a piezoelectric layer on the opposite side from the other layer when the piezoelectric layer and the other layer are bonded together with the adhesive, from overlapping an electrode formed on the surface of the piezoelectric layer on the opposite side from the other layer.SOLUTION: A laminate of a piezoelectric layer and a common electrode is manufactured and bonded to an ink separation layer with an adhesive. Then an individual electrode is formed on an upper surface of the piezoelectric layer. When there is an exuding part where the adhesive exudes on the upper surface of the piezoelectric layer, the individual electrode is formed avoiding the exuding part. After the individual electrode is formed, the individual electrode and a pressure chamber are positioned, and a flow passage unit is joined to the ink separation layer.</p> |
