摘要： In an ink jet head circuit board including a heater for generating thermal energy used for ejecting ink in response to application of electricity, a drop in thermal energy efficiency is prevented while reducing an area of the heater to achieve higher-resolution and higher-image-quality printing, and damages on the heater attributable to a manufacturing process are avoided. To achieve this, a resistor layer is disposed on an electrode wire layer; and two protective layers are disposed thereon. Then the upper protective layer is removed in a site above the heater. Accordingly, it is possible to dispose the protective layers without causing a decrease in an effective bubble generating region, and to improve thermal energy efficiency by reducing the effective thickness of the protective layer above the heater. Moreover, the resistor layer is covered with the first protective layer and is thereby prevented from adverse effects in the manufacturing process such as etching processes.

摘要： The present invention provides a substrate for ink jet including a heating resistor generating thermal energy for discharging an ink from an ink discharge port and an upper protective layer which is formed above the heating resistor and has a contacting surface with the ink. Furthermore, the upper protective layer is made of an amorphous alloy consisting of Ta and Cr in which the content of Ta is more than that of Cr. This constitution allows for the substrate excellent in cavitation resistance and corrosion resistance, and capable of high durability while having similar discharge performance to that of a conventional protective layer made of a Ta film. The present invention further provides an ink jet head comprising the above-mentioned substrate, and a manufacturing method thereof.
