A flexible wiring circuit board has a second terminal section bonded and electrically connected to a first terminal section of a wiring circuit board of a discharge die. A drive signal is inputted to the first terminal section through the second terminal section, and then sent to a driver IC. The driver IC drives a piezoelectric element in accordance with the drive signal through a printed wiring pattern. Thereby, ink is discharged from an ink discharge opening. A copper ion diffusion inhibiting film is formed on a surface of a copper wiring member of the second terminal section on contact with a process liquid containing at least one of 1, 2, 3 triazole and 1, 2, 4 triazole. This inhibits diffusion of copper ions and copper ion migration resulting therefrom. Thus, malfunction due to the copper ion migration is inhibited.
