Abstract:
A method of manufacturing an liquid jetting head, comprising the steps of:providing a first substrate, which defines a plurality of pressure generating chambers, the first substrate including a vibration plate which forms a first surface of the first substrate, and formed with a first through hole; forming a plurality of piezoelectric elements on the vibration plate so as to associate with one of the pressure generating chambers, each piezoelectric element comprised of an upper electrode, a lower electrode and a piezoelectric layer provided between the upper electrode and the lower electrode; providing a second substrate formed with a second through hole; bonding the second substrate onto the first surface of the first substrate with an adhesive agent, while forming a coating layer comprised of a resin material on an inner wall face of a region at which the first through hole and the second through hole are to be connected; and forming a communicating portion at which the first through hole and the second through hole are connected.
