Abstract
A method for manufacturing a liquid supply member that supplies a discharge port with liquid includes preparing a transparent member and an absorption member, at least one of both members having a groove for a supply path; bringing both members into contact; and forming the supply path by emitting laser beams simultaneously from a plurality of laser beam sources, toward a contact portion, which is provided in a vicinity of the groove and at which both members are in contact, to weld both members. Laser beams are emitted during the forming such that a total laser-beam irradiation amount per unit area for a first portion included in the contact portion and located in a vicinity of an end in a longitudinal direction of the groove is larger than that for part with a smallest irradiation amount of a second portion other than the first portion of the contact portion.
