PROBLEM TO BE SOLVED: To join an element substrate with a supporting member while reducing possibilities that a liquid supply passage is narrowed.SOLUTION: First light irradiation is performed from the side of an adhesive layer 4 so that light of irradiation energy larger than regions other than first regions 4a of the adhesive layer 4, or second regions 4b, is irradiated to the first regions 4a and that the first regions 4a are cured to an extent where the shapes of the regions can be retained. A laminate 1 is stuck to a substrate 8 of an element substrate 5 so that the adhesive layer 4 in the first regions 4a covers a liquid supply port. Second light irradiation is performed from the side of a base material film to the laminate 1 stuck to the element substrate 5 so that the adhesive layer 4 in the first regions 4a is integrated with a cohesive layer 3 and that an uncured constituent of the adhesive layer 4 in the second regions 4b remains on an interface between the cohesive layer 3 and the adhesive layer 4. The laminate 1 receiving the second light irradiation is separated from the element substrate 5 so that only the adhesive layer 4 in the second regions 4b is adhered to the substrate 8. The element substrate 5 is attached to a supporting member.SELECTED DRAWING: Figure 7 |
