Fastener stringer includes a fastener tape provided with a fastener element; and a stop part arranged at an end of the fastener tape. The stop part includes: a magnetic body; an encapsulating member encapsulating the magnetic body; and an injection-molded portion that at least partially covers or surrounds the encapsulating member encapsulating the magnetic body. At least the encapsulating member hinders heat from being transferred to the magnetic body while the injection-molded portion is formed.
