Zusammenfassung:	A transparent adhesive layer 3 with good permeability to laser light is provided on a base sheet 4, a colored layer 2 with good absorption of laser light is provided on the transparent adhesive layer 3, and a transparent layer 1 with good permeability to laser light is provided on the colored layer 2. Laser light 6 is irradiated from the side of the transparent layer 1 to form marked sections 5 at prescribed areas of the colored layer 2. To paste the marking sheet A onto the outer surface of a product, the base sheet 4 is peeled off and the transparent adhesive layer 3 is pasted onto the outer surface of the product. The color of the outer surface of the product may then be seen through the marked sections 5. Thus, satisfactory displays may be provided using only the marked sections 5 formed by laser light irradiation, without any additional special painting step.
