The purpose of the invention is to provide a refrigerator that can promote photosynthesis in produce such as vegetables (leafy vegetables in particular) being stored by efficiently utilizing light radiation energy without consuming excess energy. For this reason, this refrigerator comprises a storage chamber in which food products are stored and a light emitting unit (14) that can emit visible light into the storage chamber. The light emitting unit (14) comprises a first light source (16a) that emits light having a center wavelength that is a first wavelength in the visible light region and a second light source (16b) that emits light having a center wavelength that is a second wavelength, shorter than the first wavelength, in the visible light region. In addition, the light emitting unit (14) emits light from the first light source (16a) at a first radiation intensity and emits light from the second light source (16b) at a second radiation intensity that is different than the first radiation intensity during an irradiation step of emitting light.
