Abstract: PROBLEM TO BE SOLVED: To select processing in a recycling process by providing a scale visually displaying a deterioration degree to a product or a part and comparing an actual deterioration degree with the deterioration degree of the scale. SOLUTION: An ultraviolet irradiation test is applied to a test piece having material quality and a color same to those of a housing 11 for various irradiation times. A discoloration degree and a deterioration degree by a strength test are confirmed and a color sample of a limit usable as a part and a color sample of a limit reutilizable as a material are formed. A housing deterioration degree judging scale 12 is formed on the basis of the formed color samples to be added to a product. A part of the housing 11 is directly irradiated with ultraviolet rays to be discolored to form a color sample. At a time of the recycling of the product, the color of the scale 12 is compared with the color of the housing 11 to judge a recycling method.  When the yellowing degree of the color of the housing is stronger than the color sample showing a deterioration degree enabling the recycling of the part but lower than a deterioration limit enabling the recycling of the material, the housing is judged as a recycle article.
