Abstract: A slide fastener includes a pair of waterproof stringers comprising a pair of woven and/or knitted fastener tapes, a pair of coil elements respectively secured to opposing side-edge portions of the pair of fastener tapes, and waterproof films respectively overlaid via adhesives on tape top surfaces of the fastener tapes of the pair of fastener tapes, and a slider that moves forward to engage the pair of coil elements and moves rearward to disengage the pair of coil elements. Each of the waterproof films has a film edge positioned over a space between the opposing side-edge portions of the pair of fastener tapes, the film edge supported by a supporting portion made of the adhesive solidified, the supporting portion partially occupying the space between the opposing side-edge portions of the pair of fastener tapes, and the supporting portion having a thickness greater than a thickness of the film edge.
