Abstract
The ink jet print head provides a good electrical connection with the silicon substrate. A silicon substrate of the ink jet print head the electrodes for electrical connection have a layer construction such that, under a part of the metal bumps, wires drawn from the cavitation resistant film and a metal layer not corroded by the ink are formed overlapping each other. The ink jet printing apparatus uses the ink jet print head constructed as described above.
