Being production method of the liquid supply component where it can provide the groove where it becomes the supply road which supplies the liquid

摘要

PPROBLEM TO BE SOLVED: To reduce the possibility of not-yet-welded part arising in the contact part of the members located near the groove used as a supplying passage when the liquid supply member is formed by irradiating laser beams from a plurality of laser light sources arranged along the groove and welding the members each other. PSOLUTION: The contact part where the members are contacted each other is irradiated with laser beams from a plurality of the first laser beam sources arranged along the longitudinal direction of the groove. At the same time, the laser beam is irradiated toward the part located near the end of the groove in the longitudinal direction of the outside of the contact part from the second laser beam source installed near the laser beam source of the end in the longitudinal direction among the first laser beam sources.
