PROBLEM TO BE SOLVED: To produce a luminous adhesive film easily at a low cost by imparting luminous properties to a pressure-sensitive adhesive of an adhesive layer by adding a luminous pigment thereto. SOLUTION: A luminous film (a) is obtd. by forming an adhesive layer 7 contg. a luminous pigment on one side of a clear film 1 and sticking a separator 5 to the adhesive layer 7. A luminous adhesive film (b) is obtd. by sandwiching an adhesive layer 7 contg. a luminous pigment between a clear film and a white film 3, forming a normal adhesive layer 4 on the side of the white film 3, and sticking thereto a separator 5. The clear film used is selected form films of a polyester, a polycarbonate, polyvinyl chloride, etc., and has a thickness of 12-200μm. Pref., the adhesive is a clear, solvent-dilutable one such as of an acrylic or rubber-based type. Dysprosium- or europium-activated strontium aluminate. zinc sulfide, etc., are used as the luminous pigment.
