| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a fuse element which is inexpensive in the manufacturing cost and strong also in thermal shock due to heat cycle in the fuse element having a fusible part which fuses when an overcurrent flows and a heat storage part having heat capacity, and also having connection terminals connected to both ends, and also to provide a sealed wire fuse using this fuse element.SOLUTION: A fuse element is comprised of a single resistance wire 1 in which a fusible part and a heat storage part 3 are continuously formed in a integral manner. The heat storage part 3 of the fuse element is constituted of a multiply bent part 2 of the resistance wire 1 and fusible metal filled in voids of the bent part. |
