PROBLEM TO BE SOLVED: To provide a refrigerator using a light source having a relatively safe long-wavelength for improving preserving performance. SOLUTION: The refrigerator comprises storage cases 35 provided as temperature different sections in a refrigerating chamber 2. Herein, the light source 13 formed with a LED having a wavelength in a ultraviolet region is installed for inactivating the function of propagating microorganisms deposited on the wall faces in the storage cases 35 or on the surfaces of stored articles, therefore keeping a change-over chamber sanitary and delaying discoloration or putrefaction smell caused by microorganisms in foods or the production of tackiness on the surfaces of the stored articles. Thus, the storage cases can be kept always clean while improving preserving performance. COPYRIGHT: (C)2007,JPO&INPIT
