摘要

A pair of polyester resin fastener tapes (18) whose one side edges are adjacent to each other at a given interval (s), and an element attached on the main surface of the one side edge of each fastener tape (18) Waterproof coating film made of polyester resin formed on the main surface opposite to the main surface of the row of (11) and the main surface of each fastener tape (18) to which the row of elements (11) is attached (19), the outer surface of the waterproof coating (19) is at least flat where the slider 12 is to pass, and the waterproof coating (19) is a fastener. Indentations on the main surface of the fastener tape (18) at the interface with the tape (18) and into the gap (20) generated by the gap (s) between the pair of fastener tapes (18) The penetration depth (d) of the water coating (19) is less than or equal to the thickness of the fastener tape (18), and the edges of each waterproof coating (19) are from the one side edge of each fastener tape (18). Waterproof zipper chain that extends and abuts in the direction of approaching each other.
