PROBLEM TO BE SOLVED: To efficiently activate a photocatalyst by a method wherein an optical fiber flux arranged in a light projecting direction of a light source is formed in a reverse curvature manner by bundling the optical fiber so that an optical refraction index of a peripheral part becomes larger than that of an axial core part, and the photocatalyst is attached onto a peripheral surface of the optical fiber flux. SOLUTION: When applied to a showcase, a refrigerator C is arranged in a storing room 2, and connected to another part so as to constitute a refrigerating cycle. Further, for the showcase main body 1, a deodorizing device S is arranged to one side part, an opening part is provided to a side surface part, and a ventilating fan is attached to an outer surface part. The deodorizing device S is composed of a plurality of deodorizing levers 6... protruded from a front surface part of a base body 5 in which an ultraviolet lamp 8 is housed, and a reflection plate 7. Then, for the deodorizing levers 6, the photocatalyst 12 is coated by using an adhesive onto an outer peripheral surface of the optical fiber flux 11 in which a number of lines of the optical fibers 10 are bundled so as to obtain a specific wall thickness, and the optical fibers 10 are bundled so that the refraction index of the more peripheral part becomes higher than that of the axial core part. |
