Liquid-tight slide fastener

A liquid-tight slide fastener comprising:

• a pair of fastener tapes comprising a pair of woven or knitted tape members, core sections respectively provided on opposing tape edges of the pair of tape members, the core sections being expanded from the tape members, and liquid-tight layers respectively formed on one side of the pair of tape members;
• a pair of fastener element rows respectively provided on the pair of fastener tapes, and comprised of a plurality of fastener elements;
• and
• a slider which causes the pair of fastener element rows to engage with and disengage from each other,
• wherein the liquid-tight layers are formed with gaps to the core sections in a width direction of the fastener tapes such that tape-exposing sections in which the tape members are exposed are formed in a range between the core sections and the liquid-tight layers,
• wherein each of the fastener elements has a pair of base sections attached to a respective core section of the pair of tape members, and wherein the liquid-tight layers are in contact with at least one of the base sections of the respective pair of base sections, and disposed between one of the pair of base sections and a respective tape member.
