PROBLEM TO BE SOLVED: To solve a problem that when three ear parts formed when a triangular rice ball is packaged by using a packaging body are heat-welded and sealed, a knob piece as an unsealing start point constituted by including an end of an unsealing strip (a cut tape) provided on an outer sheet is stuck to an inner sheet, and its function can be impaired. SOLUTION: A notch portion 10 is formed in a part of the inner sheet 7 corresponding to the unsealing start point 6 of the unsealing strip 3 to prevent the unsealing strip 3 from being stuck to the inner sheet 7.
