A fusible link (1) includes: an elongated conducting body (10) having wire parts (15) provided at both end portions in a longitudinal direction of the conducting body (1), and a fusion-cutting part (11) provided at an intermediate portion of the conducting body (1) in the longitudinal direction, the fusion-cutting part (11) being formed by a rolling process so as to have a cross section smaller than each of cross sections of the wire parts (15) and being fusible by flow of current having a predetermined value; a low-fusing-point metal body (13) welded to the fusion-cutting part (11) and having a lower fusing point than the conducting body (10); and a fire-proof insulating body (12) configured to cover at least the fusion-cutting part (11) and the low-fusing-point metal body (13). |
