PROBLEM TO BE SOLVED: To provide a rice ball package which enables easy opening work and is capable of surly exposing a predetermined upper part of a rice ball when opening.SOLUTION: A rice ball package can enclose a rice ball in a packaging bag in a state of single packaging. Two lower opening end brims of a rectangular packaging material bent into an approximate contra-U letter shape in a cross-sectional view and tow upper opening end brims of a rectangular packaging material bent into an approximate U letter shape in a cross-sectional view are faced and subjected to heat adhesion over the right to the left with each other to be formed into a cylinder which is rectangular in a front view. Facing surface parts respectively composed of the upper, and lower packaging material parts and right and left end parts of a back surface are subjected to heat adhesion so as to be freely peeled to form an end heat adhesion part into a sealed bag. An easily peelable seal-opening heat adhesion part are provided as a seal-opening part which is a connection part of the one lower opening end brim appearing at the surface part to the one upper opening end brim. Gussets are formed at right and left under bottom corner parts as back surface heat adhesion parts which are connection parts of the other lower opening end brims appearing the back surface to the other upper opening end brims.SELECTED DRAWING: Figure 6
