This waterproof slide
fastener (1, 2, 3, 4) is configured so that first and second through-holes (14a, 14b) are formed at specific intervals in tape side edges of waterproof tapes (11), and so that first and second halves (15, 16) of
fastener elements (12) are connected and integrated together through the first through-holes (14a). A stopper (20, 30, 40, 50, 60) has a body section (21, 31, 41, 51, 61) and an extension section (22, 32, 42, 52, 62) which extends from the body section (21, 31, 41, 51, 61). First and second halves (23, 24) of the stopper (20, 30, 40, 50, 60) are disposed so as to
straddle the pair of waterproof tapes (11) and are connected and integrated together through the second through-holes (14b). As a result of this configuration, the manufacturing step of the waterproof slide
fastener (1, 2, 3, 4) is simplified, and water is prevented from entering even if the slide fastener (1, 2, 3, 4) is subjected to a lateral pulling force.
