Abstract
A liquid discharge head includes an element substrate including an energy generating element; a supporting member adhesively supporting the element substrate; a sheet member adhesively bonded to the supporting member to adjoin the inner surface of an opening accommodating the element substrate in the sheet member and an end section of the element substrate; a wiring substrate bonded to the sheet member to adjoin the inner surface of an opening accommodating the element substrate in the wiring substrate and the end section of the element substrate and including a wire electrically connected to the energy generating element; and a sealant sealing a part electrical connecting the wiring substrate and element substrate, wherein the height of a wiring substrate surface opposite to that contacting the sheet member from supporting member is smaller than the element substrate surface opposite to that contacting the supporting member from the supporting member.
