Abstract:
A liquid discharge head includes a recording element substrate including an energy generating element, a wiring substrate including wiring, a support substrate for supporting the recording element substrate and the wiring substrate so that a side end portion of the recording element substrate and a side end portion of the wiring substrate are adjacent to each other, and a sealing member, wherein the side end portion of the wiring substrate has a step portion, a distance between a second portion of the step portion on the side opposite to the support substrate and the side end portion of the recording element substrate is larger than a distance between a first portion of the step portion on the side of the support substrate and the side end portion of the recording element substrate, and a part of the wiring is formed in the first portion.
