PROBLEM TO BE SOLVED: To increase the function to protect an article to be packaged from static electricity by a method wherein a material which has a conductive sheet at least on the internal surface, is used, and at the same time, as an elastic sheet, a sheet in which a conductive substance or an anti-static agent is kneaded, is used. SOLUTION: A blank, which is punched from a material overlaid with a conductive film in the surface of a bond paper or corrugated fiberboard, is spanned with elastic sheets 8B, 9B. Then, an adhesive is applied to a gluing part 5, and a wall in the lateral direction is formed into a ring-shape. On a lower supporting body 8, an article to be packaged is placed, and after placing an upper supporting body 9, the article to be packaged is covered with an upper surface plate 6, and by doing so, a package is formed. As a material for the elastic sheet, a sheet in which a conductive substance, e.g. a powder of metal or carbon is kneaded, or an anti-static agent is kneaded, is used. When there is fear wherein the article to be packaged may be broken by the passing of static electricity charge, as the elastic sheet, a sheet in which an anti-static agent, not a conductive substance, is kneaded, is used. |
