A packaging sheet according to the present invention includes a first film, a second film, and a belt-like cover piece that airtightly joins opposing ends of the first film and the second film. A film substrate, which is sandwiched between a film substrate 11 having a bent portion L3 orthogonal to the cover piece at a substantially central position in the longitudinal direction of the cover piece, and the film substrate bent at the bent portion. A sheet-like food 50 and a heat-welded portion 13 that hermetically joins three sides of the film base other than the bent portion, and the first film and the second film wrap a rice cake. The easily breakable portions 24 and 34 for easily breaking the first film and the second film are formed in the joint portions 22a and 32a with the cover piece located on the inner side. That.
