A lid member for a press-through package, and a press-through package packing body using the same in which the lid member is not to be inadvertently torn, while tablets or capsules as its contents can be taken out under a uniform opening strength by a predetermined force or more using fingers. The lid member (10) of the packing body (1) includes a resin film (11), an adhesive (12), an aluminum foil (13), and a thermal adhesive layer (14), in which tapered through holes (11a) are formed in the resin film (11). The resin film (11) is laminated to the aluminum foil (13) to reinforce the lid member (10) so that the lid member (10) is not to be inadvertently torn, while, when contents (30) of a container (20) are pushed out using fingers, the lid member (10) is broken starting from the tapered through holes (11a) provided in the resin film (11), and thus the contents (30) can be easily taken out.
