A gas permeability control film (165) having a barrier property against water, bacteria, and viruses, an oxygen gas permeation amount controlled to fall within the range of 10<3> to 10<7> cc/m<2>.24 hours.25 DEG C, and a controlled carbon dioxide gas permeation amount. The gas permeability control film (165) has an organic film (160) in which non-through pores (166) having an average opening width falling within the range of 0.5 mu m to 150 mu m are formed at a density of 500 to 200,000 pores/cm<2>. <IMAGE> |
