PROBLEM TO BE SOLVED: To provide a blister packaging body which is difficult to generate a distortion in thermally welding a case member formed by a synthetic resin sheet to a lid member even when a recess of an article storage portion is shallow. SOLUTION: A blister packaging body comprises a case member 10 provided with a circular article storage portion 11 which is formed of a synthetic resin sheet by a compressed air forming method and recessed forward to store a button cell and a flange portion 12 to be outwardly expanded from a circumferential edge of this article storage portion 11, and a lid member 20 which is formed of a synthetic resin sheet to be lapped on a back side of the case member 10. The lid member 20 lapped on the back side of the case member 10 and an outer peripheral portion 12b of the case member 10 are thermally welded and fixed in a condition where the button cell is stored in the article storage portion 11, and welded portions 1a are studded on an upper edge portion, a lower edge portion and both side edge portions of the outer peripheral portion 12b of the case member 10.
