Abstract
A method of making a liquid supply member includes preparing a transparent member including a first surface having a first opening portion and an absorption member including a second surface having a second opening portion, making the transparent member and the absorption member contact each other at a contact portion so that the first opening portion and the second opening portion overlap each other with respect to an intersecting direction that intersects the first surface and the second surface, and forming a first supply path by welding the transparent member and the absorption member to each other by irradiating the contact portion with a laser beam, the first supply path including the first opening portion and the second opening portion and being a path through which liquid flows in the intersecting direction, wherein a space is formed between the contact portion and the first supply path and between the first surface and the second surface.
