A slide fastener for preventing core strings from being caught in a gap between upper and lower flanges, securing the flexibility of the slide fastener when engaged, and improving the designability of the slide fastener. The gap dimension between the upper and lower flanges of a slider in the up-down direction is smaller than the core string dimension in the front-rear direction when the core strings are pressed with the pressure of 5 kgf. Fastener elements are independently disposed in the up-down direction of a tape member when engaged. The fastener element has a design portion disposed at a front side of the tape member, and an engaging portion disposed at a rear side of the tape member so as to engage with adjacent fastener element, and the design portion is disposed distant from the adjacent design portion when engaged and having a hemispherical shape with a curved shape.
