Abrégé
(EN)
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.
(FR)
Un procédé de fabrication d'un élément de fourniture de liquide qui fournit un orifice d'évacuation en liquide comprend la préparation d'un élément transparent et d'un élément d'absorption, au moins l'un des deux éléments comprenant une rainure pour un trajet de fourniture ; l'entrée en contact des deux éléments ; et la formation du trajet de fourniture par l'émission simultanée de faisceaux laser à partir d'une pluralité de sources de faisceaux laser, en direction d'une partie de contact, qui est disposée dans le voisinage de la rainure et au niveau de laquelle les deux éléments sont en contact, afin de souder les deux éléments. Les faisceaux laser sont émis pendant la formation de sorte qu'une quantité totale d'exposition aux faisceaux laser par région unitaire pour une première partie comprise dans la partie de contact et disposée dans le voisinage d'une extrémité dans une direction longitudinale de la rainure soit supérieure à celle pour la partie présentant la plus petite quantité d'exposition d'une seconde partie autre que la première partie de la partie de contact.
