This invention relates to a top end stop having a substantially U-shaped section and a bottom end stop having a substantially lateral-H shaped section. In each end stop, leg portions having key-shaped sections, i.e., a hook shaped portion is provided at front ends thereof, are extended in a bent manner from a rectangular base portion, so that an accommodation portion surrounded by the base portion and a pair of leg portions is provided for accommodating a core portion. A row of a projecting portion is formed continuously/intermittently on an inner face of the base portion and a gap portion is provided between the projecting portion and the root of each leg portion. The projecting portion positions the core portion accurately and holds it, and in crimping the leg portions, the core portion is compressed, and the gap portion is filled thereby, so that the core portion is secured firmly.

End stop for slide fastener

A wireless IC tag mounted on a low magnetic permeability material is mounted on a holding part which has first and second surfaces and is made of a high magnetic permeability material. The holding part has a penetrating part which penetrates the first and second surfaces, and a notch which penetrates a part of the first and second surfaces at a periphery. A discontinuous region is formed on the holding part due to the notch, and at least on the penetrating part, the wireless IC tag is tightly held together with the low magnetic permeability material. An axis of reverse direction magnetic flux generated by an eddy current that flows in the periphery of the penetrating part and the notch is shifted from an axis of the magnetic flux produced by electromagnetic waves directed toward the wireless IC tag on the first and second surfaces.
