PROBLEM TO BE SOLVED: To provide a refrigerator capable of efficiently utilizing light radiation energy without consuming surplus energy to accelerate photosynthesis of stored fruits and vegetables such as vegetable (especially, leaf vegetables).SOLUTION: A refrigerator includes a storage chamber configured to store foods, and a light-emitting unit 14 capable of irradiating the inside of the storage chamber with visible light. The light-emitting unit 14 includes a first light source 16a configured to radiate light with a first wavelength in a visible light region as a center wavelength, and a second light source 16b configured to radiate light with a second wavelength in the visible light region shorten than the first wavelength as a center wavelength. Then the light-emitting unit 14, in an irradiation step of radiating light, radiates light at first radiation strength from the first light source 16a, and at the same time, radiates light at second radiation strength higher than the first radiation strength fr
