A lid member for a press-through package, and a press-through package packing body using the same, includes a lid member which is not to be inadvertently torn, while tablets or capsules as its contents can be removed under a uniform opening strength by a predetermined force or more using fingers. The lid member of the packing body includes a resin film, an adhesive, an aluminum foil, and a thermal adhesive layer, in which tapered through holes are formed in the resin film. The resin film is laminated to the aluminum foil to reinforce the lid member so that the lid member is not to be inadvertently torn. When contents of a container are pushed out using fingers, the lid member is broken starting from the tapered through holes provided in the resin film, and so the contents can be easily taken out.
