Abstract
An ink jet printing head substrate has a high adhesion between an electrode layer and a nozzle formation member and the corrosion or electrolysis, for example, of an electrode due to the contact between the electrode and ink can be reduced. The ink jet printing head includes an electrode layer for supplying power to a heat-generating portion that is provided on a substrate and that generates thermal energy for ejecting ink; and a resin layer provided on the electrode layer via a nickel-containing layer. The electrode layer includes precious metal as a main component. The nickel-containing layer consists of a gold-nickel alloy containing nickel.
