PROBLEM TO BE SOLVED: To solve such the problem that in a substrate for a liquid jetting head, which includes an element for generating energy for jetting a liquid and a conductive layer electrically connected to the element and is provided by layering, thereon, a metallic material layer in contact with the conductive layer, a gold layer and a nickel layer, the metallic material layer is also etched when the nickel layer is etched. SOLUTION: A resin layer 111 is formed on the end face of the metallic material layer 106, and a part of a layer 110 containing nickel is removed by etching. COPYRIGHT: (C)2011,JPO&INPIT |
