PROBLEM TO BE SOLVED: To provide a bar soap wrapping sheet having moisture-proofness, retentivity, and an excellent production efficiency, and having a structure using neither a metal foil nor a metal vapor deposition layer.SOLUTION: A vapor deposition film 4 is laminated through an adhesion layer 3 on the back of a paper substrate 2 having a pattern printing layer 1 formed on a surface. A vapor deposition film is formed, on a deposition base material layer 41, with an inorganic oxide vapor-deposition layer 42, and on the face of the inorganic oxide vapor-deposition layer, with a protective layer 43 which is prepared by applying a coating agent composed mainly of either one or more kinds of metal-alkoxide or an aqueous solution containing at least any of a hydrolysate, and a water-soluble polymer, and by heating and drying the same. |
