Provided is a refrigerator such that the photosynthesis of stored fruit and vegetables can be facilitated by taking into account the states of the stomata of plants using the circadian rhythm of plants. This refrigerator (1) is equipped with: a light-emitting unit (14) which is capable of irradiating with visible light the interior of a storage chamber (500) where food is stored; and a control unit (8) which controls the operation of the light-emitting unit so that a visible light irradiation process, in which light including visible light is irradiated from the light-emitting unit, and a non-irradiation process, in which light including visible light is not irradiated from the light-emitting unit, are alternately repeated. The light-emitting unit is equipped with: a first light source (16a) in which light with a first wavelength in the visible light region is irradiated as the central wavelength; and a second light source (16b) in which light with a second wavelength in the visible light region is irradiated
