PURPOSE:To improve the reliability of an adhesive layer to make the work easy by sticking a windshield to the timepiece side with the adhesive layer consisting of a photosensitive resin to which anaerotropism is given and which is hardened by inert atmosphere and ultraviolet rays. CONSTITUTION:A photosensitive resin adhesive layer 3 to which anaerotropism is given is interposed between an inside 4a of a clock side 4 and an outside 1a of a glass 1 to stick to glass 1 to the clock side 4. In this case, ultraviolet rays are irradiated to the photosensitive resin adhesive in the inert atmosphere. The adhesive in parts which are not shielded from ultraviolet rays is hardened by ultraviolet rays. The adhesive in parts shielded from ultraviolet rays by a metallic film 2 is hardened because anaerotropism is given to the adhesive and the atmosphere is inert. As the result, peeling between the adhesive layer and the metallic layer or between the metallic film and the glass is not caused. |
