PROBLEM TO BE SOLVED: To provide a current fuse which inhibits energy loss.SOLUTION: A current fuse 100 includes: an insulation substrate 1; two metal plates 2, 2, each of which is provided on an upper surface of the insulation substrate 1 and has a thick part 21 having a connected region 23 on its upper surface and a thin part 22 that is thinner than the thick part 21; and a fuse element 3 where both end parts are respectively and electrically connected with the thin parts 22. Since the structure eliminates the need to electrically connect an upper surface of the insulation substrate 1 with a lower surface, energy loss is inhibited when a current flows through the current fuse 3. |
