PROBLEM TO BE SOLVED: To enable small area formation of a heating part by enabling the heating part to be precisely formed in a substrate for an inkjet head which has the heating part for generating a heat energy to be utilized for discharging ink according to energization, and also to suppress corrosion or its spread of an electrode wiring line.;SOLUTION: A first electrode 101 of a thin film formed of a corrosion resistance metal is arranged on a base. A second electrode 103 formed of Al is superposed on the first electrode, and moreover a heating resistor layer 107 is disposed. The heating part is formed by a gap of the first electrode. The heating part is formed without a large dimensional variation brought about. Even if a defect of a protecting film is generated on the heating part or in the vicinity, since a material of the heating resistor layer is stronger to errosion than Al and moreover the first electrode has the corrosion resistance, the spread of corrosion can be suppressed.;COPYRIGHT: (C)2006,JPO&NCIPI
