Abstract: A miniaturized package of a photosensitive material, which comprises a silver halide photosensitive material comprising a transparent synthetic resin support having at least one photosensitive silver halide emulsion layer formed thereon and a sealed container containing the photosenstive material, the support having a water content of 0.3 to 1.5% by weight and the content volume of the sealed container being 0.08 x cm.sup.3 or less when the area of one surface of the photosensitive material is x cm.sup.2. By this miniaturized package, the size and weight of camera can be reduced. The photographic properties of the photosensitive material contained in the package are not easily deteriorated.
