Abstract
Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section of a cover member is inserted into an opening of a liquid-supply member, the closest distance to the opening in the area where secondary resin is injected is made larger than the gap between the opening and the convex section. As a result, the resin is prevented from flowing into a liquid path during the secondary molding.
