    摘要： Provided is a liquid ejection head having a structure in which an organic resinous member is formed in contact with a substrate. The substrate includes heat generators for generating heat energy used to eject ink, when being energized, and a metallic line portion for energizing the heat generators. The organic resinous member is provided with ejection openings corresponding to the heat generators. In the liquid ejection head, the substrate and the organic resinous member have an improved adhesion therebetween, and are prevented from being separated from each other. To improve the adhesion, the metallic line portion is cut so that no line portion exists under an end part of the organic resinous member (nozzle formation member). Then, two members of the line portion thus cut are connected to each other through a roundabout line formed under an insulating layer which has a good adhesion to the organic resin.

    摘要： It is an objective of the present invention to provide an ink jet printing head substrate by which a high adhesion can be obtained between an electrode layer and a nozzle formation member and the corrosion or electrolysis for example of a electrode due to the contact between the electrode and ink can be reduced. To realize this, the present invention 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 gold-nickel alloy containing nickel.
