A process, which produces a liquid ejection head including a recording element substrate having a principal surface and a support member having a color separation wall for ink flow paths and an outer wall, the substrate being narrower than the support member, a plane formed by conducting translation of a lower side of a substrate outer surface perpendicularly to the principal surface having an intersection with an outer wall top surface at a position distant from an inner edge of the outer wall top surface by an outward distance, includes applying an adhesive onto top surfaces of the outer and color separation walls such that a surface height of the adhesive at the intersection is higher than that at a position distant from an inner edge of the color separation wall top surface by the outward distance, and bonding and fixing the substrate to the support member with the adhesive.
A process for producing a liquid ejection head comprising a recording element substrate having a principal surface provided with an ejection orifice for an ink and a support member having a plurality of flow paths for supplying the ink to the recording element substrate, the support member having a color separation wall and an outer wall, the recording element substrate having a width narrower than a width of the support member, a plane formed by subjecting a lower side of an outer lateral surface of the recording element substrate to parallel translation in a direction perpendicular to the principal surface having an intersection line with a top surface of the outer wall at a position distant from an inner edge of the top surface of the outer wall by a predetermined outward distance, the process comprising;
A liquid ejection head comprising a recording element substrate having a principal surface provided with an ejection orifice for an ink;
A process for producing a liquid ejection head comprising a substrate having an element for generating energy to be utilized for ejecting a liquid and a first supply port and a second supply port extending side by side for supplying the liquid to the element, and a support member that has a first opening portion communicating with the first supply port and a second opening portion communicating with the second supply port and supports the substrate, the process comprising:
