Abstract
A method is provided for manufacturing a liquid supply member including a transmissive member and a transmissive member, one of which having a groove, and configured to supply liquid to a liquid ejection port. The method includes bringing the transmissive member and the absorptive member into contact, with the groove inside; forming a supply passage by radiating laser light, via the transmissive member, from a plurality of first laser light sources disposed along a longitudinal direction of the groove toward a first contact portion at a periphery of the groove to weld the transmissive member and the absorptive member; and radiating laser light, via the transmissive member, from a second laser light source provided in a vicinity of a laser light source at an end of the groove in the longitudinal direction toward a vicinity portion of the absorptive member.
