To facilitate the division of a packaging body, and at the same time, increase the mechanical strength of the packaging body.

This packaging body 1 is used for packaging batteries such as a button-shape battery or a coin-shape battery. The packaging body 1 comprises two layers of a cover 5 and a mount 4, and on respective layers, perforations 2 and 3 constituted of the connections of cut sections and remaining sections are provided. The perforations 2 and 3 are used to divide the packaging body 1. Between respective perforations 2 and 3 at the boundary of the two layers, a slip resistant-region is provided. The width of the slip resistant-region is preferably in a range of 0.5 to 2.0 mm. The cross sectional area of the remaining section of the cover 5 made of a synthetic resin from among the two layers is made smaller than the cross sectional area of the remaining section of the mount 4 made of paper. Also, at least one end of the perforations 2 and 3 is formed into a cut section.
