a passage unit that has an individual ink passage including an ink ejection port and a pressure chamber, and also has a surface on which the pressure chamber is provided in a form of a recess;

a piezoelectric actuator that applies ejection energy to ink in the pressure chamber, the piezoelectric actuator including a piezoelectric body that is disposed on the surface of the passage unit to thereby close the recess, an electrode that is formed, so as to be opposed to the pressure chamber, on a surface of the piezoelectric body facing against the passage unit, and a conductive land that is formed on the electrode; and

a wire member that includes a substrate and a wiring formed on the substrate and provided thereon with a terminal electrically connected to the land,

the method comprising the steps of:

forming, on the electrode, the land made of a resin paste including a conductive material, in a state where a whole of a face of the piezoelectric actuator opposite to a face thereof formed with the land is supported on a support member;

bonding the passage unit and the piezoelectric actuator to each other by pressing the land except a part thereof in a state where the piezoelectric actuator is disposed on the surface of the passage unit with the electrode being opposed to the pressure chamber; and

electrically connecting the land to the terminal by bringing the part of the land not pressed in the step of bonding into contact with the wire member.
