PROBLEM TO BE SOLVED: To provide an auto-lock type slide fastener having a superior recycling performance and dye property, providing clothes subjected to a safety test by a metal detector and having all the component made of resin. SOLUTION: This slide fastener includes a lock pin and/or a spring composed of molecularly oriented polyethylene terephthalate-based resin having a half value width of azimuthal distribution of an X-ray diffraction strength of 30°or less in a crystal surface 100 (spacing of approximately 3.40Å). This fastener includes the lock pin and/or the spring composed of molecularly oriented polyethylene terephthalate-based resin having a tensile elasticity at 23°C in the molecular orientation direction of 3.5 GPa or more.
