Abstract:
To provide a method for manufacturing a double-sided adhesive material suitable for the size and shape of various articles using a simple process without reducing the yield of the adhesive material that is used, and to provide an article with a double-sided adhesive material that uses the double-sided adhesive material obtained by this manufacturing method. [Resolution means] Liquid photo curing adhesive 12 is applied by direct drawing onto a specific region corresponding to the size and shape of an article to be used, on the surface of a first plate 10, using a robot. A sheet shaped second plate 20 is placed on the first plate 10 where the adhesive 12 was applied, such that the adhesive 12 is interposed between both plates. Light for curing the adhesive is then irradiated from both sides of the adhesive 12 so that the light will pass through both the first plate 10 and the second plate 20 and reach the adhesive 12.
