Abstract
There is provided a liquid ejection head that can reduce trouble in alignment of a print element substrate even in the case where a high magnification optical system is used and a method for fabricating the liquid ejection head. To achieve this, an auxiliary mark that indicates a relative position with respect to a reference mark is detected and recognized, and thus the position of the reference mark is identified even in the case where the reference mark is not reflected in a camera.
