Abstract: Disclosed is a highly durable blade fuse for which a fused site in a narrow section and the rated current are determined in conformity with its design and the temperature of which does not increase greatly when a current flows through it. A blade fuse according to the present invention includes terminal sections (A, B) and a connection section (1), which are made of the same metal base material that is zinc or a zinc alloy. Furthermore, a low-melting-point metal piece (3), made of tin, which has an outer size identical or similar to a width of the connection section (1) is melted and stuck on at least one surface of the connection section (1) outside the fused section (2), and is positioned to partially traverse an edge of the fused section (2) or not to traverse the edge but to be adjacent to the edge.
