摘要：
A belt-shaped base of a male member of a zipper tape attached on an inner surface of a bag body includes a main body provided with an engagement portion, a thin portion connected to an opening-side of the main body, a thick portion connected to an opening-side of the thin portion and a projecting portion provided on the thick portion. A female member is also provided with the same arrangement. When the zipper tape is fused with the bag body, a gap is provided between the thin portion and a film of the bag body and between the thin portion and a film of the bag body, so that the thin portions are easily bent.
