<;P>;PROBLEM TO BE SOLVED: To provide a rice ball wrapping film which is easily manufactured at low cost, and to provide a wrapped rice ball using the wrapping film which can easily be peeled from a rice ball. <;P>;SOLUTION: In a wrapped rice ball 100, when a grip part 12 is pulled in one direction, a wrapping film 1 can easily be separated into exterior films 11(a) and 11(b) which constitutes the wrapping film 1. Interior films 21a and 21b for accommodating a seaweed sheet, which are joined with the respective exterior films 11, are also separatable; thereby, the rice ball can easily be peeled from the wrapping film 1 with the seaweed sheet. The exterior films have an folded/overlapped portion 13 which has folding lines W, X, Y and Z, and slits S are formed along the folding line X. When the grip part of the wrapped rice ball is pulled, the folded/overlapped portion is deployed, and the wrapping film is divided into two parts along the slits S; thereby, the wrapping film can easily peeled from the rice ball. <;P>;COPYRIGHT: (C)2010,JPO&INPIT
