There is provided a slide fastener capable of preventing core strings from being caught in a gap between upper and lower flanges, securing the flexibility of the slide fasteners when engaged, and improving the designability of the slide fasteners. The dimension (L4) of a gap (S3) between the upper and lower flanges (33a, 33b) of a slider (30) in the up-down direction is smaller than the dimension (L5) of the core strings (13a) in the front-rear direction when the core strings are pressed with the pressure of 5kgf or more. Fastener elements (15) constituting a fastener elements row (14) are independently disposed in the up-down direction of a tape member (12) when engaged. The fastener elements (15) has a design portion (16) disposed at a front side of the tape members (12), and an engaging portion (17) disposed at a rear side of the tape member (12) so as to engage with adjacent fastener elements (15), and the design portion (16) is disposed distant from the adjacent design portion (16) when engaged and having a hemispherical shape with a curved shape. |
