Zusammenfassung:	A fuse has a pair of lead terminals disposed on a substrate, an intermediate layers for welding formed on the surface of at least one of the lead terminals, and a fuse element. The fuse element is welded to the pair of lead terminals through the intermediate layer so as to span the same. Further, the intermediate layer is formed on at least one of the lead terminals except a face thereof opposing each other. Owing to this configuration, after the fuse has melted down, the melted fuse element is prevented from being spread out into the space between the opposing faces of the lead terminals and insulation therebetween is secured.
