Abstract: A base plate (6) for use of a recording head, which is used for an ink jet head for printing by discharging ink to a recording medium, being provided with energy converting element (2) for discharging ink by generating a bubble (12) in ink with the conversion of electric energy to thermal energy, and an anti-cavitation film (1) to protect the energy converting element from shocks generated at the time of bubble growth and extinction, said anti-cavitation film being used as electrodes for detecting the state of ink by energizing the ink, comprises a first diode (14) having the anode thereof connected to the anti-cavitation film and the cathode thereof connected to the ground potential, and a second diode (13) having the cathode thereof connected to the anti-cavitation film and the anode thereof connected to the power supply potential. With the structure thus arranged, it is made possible to reduce the possibility that the circuit element formed on a semiconductor substrate is destroyed by electrostatic discharge.

Abstract: An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection. This board has the heaters formed with high precision to reduce their areas. It has provisions to protect the electrode wires against corrosion and prevent a progress of corrosion. The substrate is deposited with the thin first electrodes (101) made of a corrosion resistant metal. Over the first electrodes the second electrodes (103) made of aluminum are formed. The second electrodes are deposited with a resistor layer (107). The heater is formed in the gap between the first electrodes. With this construction, the heaters are formed without large dimensional variations among them. Should a defect occur in a protective layer above or near the heaters, a progress of corrosion can effectively be prevented because the material of the resistor layer is more resistant to encroachment than aluminum and the first electrodes are corrosion resistant.
