PROBLEM TO BE SOLVED: To avoid a problem wherein a leakage current flows into a circuit to be protected after a fusion part is fused, by suppressing its rejoining after the fusion part is fused, and to lower the height of a fusing element, in the fusing element having the fusion part to interrupt inflow of an excess current. SOLUTION: In this fusing element having the fusion part fused by an excess current, the fusion part is coated with a resin material containing glass micro-balloons to structure the fusing element. Since the glass micro-balloons around a fused spot are destroyed when the fusion part is fused and a slight space is formed, rejoining after it is fused is suppressed. COPYRIGHT: (C)2005,JPO&NCIPI
