Liquid discharge head and method of manufacturing the same

A method for manufacturing a liquid discharge head, the liquid discharge head including a liquid discharge substrate and a flow path, the liquid discharge substrate including a discharge port for discharging liquid, and the flow path supplying liquid to the liquid discharge substrate, the method comprising the steps of:

• preparing an absorption member being capable of absorbing a laser beam, wherein a first flow path portion constituting a portion of a wall of the flow path is formed on a surface of the absorption member;
• preparing a transparent member being transparent to a laser beam, wherein a second flow path portion constituting another portion of the wall of the flow path is formed on a surface of the transparent member;
• and
• forming the flow path by welding the surface of the absorption member and the surface of the transparent member with each other at a periphery of the first flow path portion using a laser beam emitted through the transparent member toward the first flow path portion and the periphery of the first flow path portion, wherein the second flow path portion is constituted by a depression in a principal plane of the surface of the transparent member, and the depression includes an inclined surface inclined with respect to the principal plane of the surface of the transparent member in such a manner that the inclined surface is capable of reflecting a laser beam directed toward the first flow path portion.
