To provide a refrigerator capable of sterilizing a shelf in a cold room without deteriorating lighting performance of the cold room.SOLUTION: A refrigerator includes a visible light source for irradiating a cold room with visible light, and an ultraviolet light source for irradiating the cold room with ultraviolet rays. The visible light source and the ultraviolet light source have structures of being disposed on a top surface of the cold room. A covering part having transmissivity and a light diffusion function is provided in a position direction facing irradiation ports of the visible light source and the ultraviolet light source. The covering part has a first transmission area to be an irradiation range of the ultraviolet light source, and a second transmission area excluding the first transmission area. Second diffusion light transmitting the second transmission area is irradiated in a mottled state due to concentration of light, and first diffusion light transmitting the first transmission area is evenly irradiated in a non-mottled state having concentration of light smaller than that of the second diffusion light.SELECTED DRAWING: Figure 3 【課題】冷蔵室の照明性能を低下させることなく、冷蔵室内の棚を除菌することができる冷蔵庫を提供する。【解決手段】実施形態の冷蔵庫は、冷蔵室に可視光を照射する可視光源と、前記冷蔵室内に紫外線を照射する紫外線光源と、を持つ。前記可視光源および前記紫外線光源は、前記冷蔵室の天面に設けられた構成を持つ。前記可視光源および前記紫外線光源の照射口に対向する位置方向には、透過性及び光拡散機能を有する覆い部を備える。前記覆い部は、前記紫外線光源の照射範囲となる第１透過領域と、前記第１透過領域を除く第２透過領域と、を持つ。前記第２透過領域を透過する第２拡散光は、光の集中によりまだら状に照射され、前記第１透過領域を透過する第１拡散光は、前記第２拡散光よりも光の集中が小さく非まだら状で均一に照射される。【選択図】図３
