The present invention provides an easy-to-produce PTP which exhibits good hermetic sealing performance and which can be readily and reliably opened (without variation) even if the working accuracy is reduced, and also provides its production method. The PTP includes a lid member 3 having a resin film 3a, an aluminum foil 3b, and a thermal adhesive layer 3c, and a container 5 having a flange portion 5b and a large number of pocket portions 5a. The resin film 3a is provided with a plurality of cut pattern units constituting weakening point-cuts 3h arranged in a string 3j. The pitch P1 of the weakening point-cuts 3h along the string is smaller than the pitch of the pocket portions, and at least one of the weakening point-cuts or at least a part of the weakening point-cut falls within a position corresponding to each of the pocket portions.
