Abstract
Legs of a pair of legs are provided with core-thread-pressing surfaces that slant gradually to approach one another as being away from the stopping surfaces. Each core-thread-pressing surface extends from the stopping surface to the base end of the leg. A thickness of each leg in a thickness direction of the fastener tape gradually increases from the free end toward the base end of the leg in accordance with at least the slanting of the core-thread-pressing surface.
