Abstract: As to a packing container, when a corrugated cardboard sheet where metallic foil is stuck on one of its sides is assembled so as to have a box-shape, an edge left for applying paste and a side on which the edge left for applying paste is stuck are connected by metallic foil tape so that metallic foil on the sides inside the box joins along an internal circumferential surface of the box. As a result, since a closed path is formed along the internal circumference of the packing container, partial charging of a packing container is prevented by short-circuiting or shielding charged static electricity, and an electrostatic breakdown of contents, such as a semiconductor device, is prevented.
