PROBLEM TO BE SOLVED: To provide a food container which elongates the storage time of a stored material and prevents the stored material from being discolored. SOLUTION: A bottomed container 1 and a lid body 2 constituting a food container A holds its transparency at some degree by mixing powder of sansen stone (made in Taiwan) in its transparent body made of a resin, glass, etc., transmitting a visible light. Light shielding layers 3 are provided outside the bottomed container 1 and the lid body 2 so that the circumferential light around the food container 1 is prevented from reaching the sansen stone layer. The sansen stone occupies an extremely large surface area by pulverization and far infrared radiation emitted by each powder is radiated to an inner space through the transparent body. A materialαstored in the food container A is thus exposed to the far infrared radiation space so that the freshness of the foods is held for a long time. The circumferential light around the food container A is prevented from reaching the sansen stone powder so that amplifying action of the far infrared radiation is suppressed and troubles such as baking of the stored materialαby the far infrared radiation is prevented from generating.
