<p>The invention intends to provide a linear slide fastener in which a size of a fastener element is reduced thereby saving resources and achieving a smooth sliding of a slider, wherein a concave portion (14) that accommodates a fixing thread (5) for fixing a fastener tape (4) is provided on a top face of an upper leg portion (12) of a coil-like or zigzag-like linear fastener element (1), when dimensions from a bottom face of a lower leg portion (13) up to a top face of the upper leg portion (12) on a side of a coupling head (10), at the concave portion (14) and on a side of an inverted portion (11) are assumed to be H1, H2 and H3 respectively, a setting condition of H1 > H3 > H2 is satisfied and when dimensions from a bottom face of the upper leg portion (12) to a top face of the lower leg portion (13) within a gap portion (16) on the side of the coupling head (10), at a convex portion (15) and on the side of the inverted portion (11) are assumed to be H4, H5 and H6 respectively, a setting condition of H4 > H6 > H5 is satisfied.</p> |
