PROBLEM TO BE SOLVED: To provide a slide fastener capable of sufficiently securing attachment strength of a fastener element to a fastener tape having a liquid-tight layer, and endurable with long term use.SOLUTION: A slide fastener includes: a pair of fastener tapes 20 which have a pair of tape members 21, expanded core parts 22 provided on tape marginal parts opposed to the pair of tape members respectively, and liquid-tight layers 23 each formed on one surface of each of the pair of tape members; a pair of fastener element rows which are provided on the pair of fastener tapes, and constituted from a plurality of fastener elements 31; and a slider which engages/separates the pair of fastener element rows. The liquid-tight layers are formed with an interval in the width direction of the core part and the fastener tape, the fastener elements are attached to the core part, and a marginal part 23a on a core part side of the liquid-tight layer is formed on the core part side than the outer end part of the flange of the slider. |
