Abstract
A stopper portion has a minute protrusion on part of an outer peripheral face except a side face in the length direction of a fastener tape. This protrusion is a rib-like protrusion extended linearly in the length direction of the fastener tape formed on a vertex of the surface of a bent portion, a protrusion extended so as to be expanded in a curved shape in the length direction of the fastener tape or a rib-like protrusion protruded along a boundary portion between the bent portion of the stopper portion and a bottom face thereof. Existence of this protrusion not only reduces a sliding resistance when the slider is started but also eliminates prickly feeling and feeling of disharmony originating from a shape of an upper stopper which is a kind of the conventional stopper portion.
