摘要： There is provided a substrate for an inkjet printing head and a method for manufacturing the same, in which the substrate has a structure that different kinds of metals do not come into contact with ink or moisture. For this purpose, the structure is constituted such that a diffusion preventing layer for mainly protecting a lower layer among power wiring metals is covered by a metal layer for mainly supplying power, in connection with its upper surface and at least part of a side surface. Herewith, since a single metal appears on a surface of the power wiring including up to its side surface, even circumstance occurs of coming into contact with the ink or the moisture, a battery reaction accompanied by difference of ionization tendency is not generated, and thus corrosion or short-circuit of the power wiring is suppressed.
