Abstract
A waterproof slide fastener where first and second through-holes are drilled in a tape side edge portion of a waterproof tape at specific intervals from one another, and first and second halves of a fastener element are integrally connected to each other through first through-holes. A stopper includes a body portion and an extension portion extending from the body portion. First and second halves of the stopper straddle a pair of waterproof tapes and are integrally connected to each other through second through-holes. According to the waterproof slide fastener, a manufacturing step thereof can be simplified, and it is possible to effectively prevent water from entering the waterproof slide fastener even if it receives a lateral pulling force.
