PROBLEM TO BE SOLVED: To enable contents to pass from the only opening provided with a zipper without contact with a sealing surface of the zipper. SOLUTION: The bag with the zipper consists of a belt-like sheet 2a having a protruding line 3 glued to one of internal surfaces of the opening to cross the opening and a belt-like sheet 2b having a recessed groove 4, wherein the protruding line 3 and the recessed groove 4 keep such a positional relation that they can be fitted with each other. While the internal side of a bag body 1 is opened from a sealed portion where the line 3 and the groove 4 are fitted with each other, the belt-like sheet 2b having the groove 4 is provided on the same surface as that of the sheet 2a having the protruding line 3.
