A belt-shaped base (321) of a male member (32) of a zipper tape (3A) attached on an inner surface of a bag body (2) includes a main body (3211) provided with an engagement portion (31), a thin portion (3212) connected to an opening-side of the main body (3211), a thick portion (3213) connected to an opening-side of the thin portion (3212) and a projecting portion (3214) provided on the thick portion (3213). A female member (33) is also provided with the same arrangement. When the zipper tape (3A) is fused with the bag body (2), a gap is provided between the thin portion (3212) and a film of the bag body (2) and between the thin portion (3312) and a film of the bag body (2), so that the thin portions (3212) and (3312) are easily bent.
