Abstract
A multifilament yarn composed of multiple filaments as thin as 0.5 to 1.5 dTex is used for all warp knitting yarns () and warp weaving yarns (to-N) of a tape main body (A). As for an exposed portion on a side of a coupling head of each element covered with multiple fixing yarns (), when it is assumed that a distance from a front end of each coupling head (Eh) to an inside face of a connecting portion (Ec) is (a) while a dimension of a covered portion of an element (E) covered with the fixing yarns () in a direction of a leg portion (El) thereof is (b), a value of a ratio (b/a) is larger than 1/2 and 4/5 or less. As a consequence, it is possible to obtain a knitted/woven concealed type slide fastener in which fastener elements are attached strongly in a stable manner, and even if a strong lateral force is applied to the slide fastener during usage, a coupling portion of a fastener element row is difficult to be seen from outside, the knitted/woven concealed type slide fastener being thin and plastic.
