Abstract
The invention provides a fastener stringer for a concealed slide fastener in which right and left fastener tapes respectively include a tape body portion, a tape bend portion bent into a U-shape and an element mounting portion, a hollow weave portion is formed at each fastener tape, and a film body is accommodated in the hollow weave portion in a state of being sewn together with a fastener element as one side edge thereof being located to the tape bend portion side from a sewing thread. Accordingly, since stiffness of the hollow weave portion is improved by the film body, a closely-contacted state between the right and left tape bend portions is stably maintained and concealing characteristics of the concealed slide fastener can be improved.
