<p><P>PROBLEM TO BE SOLVED: To provide a refrigerator showcase having a high defogging performance by providing the particulates of tungstic oxide or a tungstic oxide composite material at least on the outer side surface, and maintaining hydrophilicity for a long period of time. <P>SOLUTION: In the refrigerator showcase including the particulates of the tungstic oxide or the tungstic oxide composite material at least on the outer side surface, the mean particle size of the particulates is in the range of 1 nm to 200 nm, and the aspect ratio of the particulates is in the range of 1-3.5. When using the particulates of the tungstic oxide or the tungstic oxide composite material which is excellent in a photocatalytic performance under irradiation with visible light, soil with organic matter and gas decomposition and antibacterial-sterilizing performance can be added. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
