Claim:
1. A blade fuse comprising: a pair of terminal sections positioned at both ends of the blade fuse; a connection section formed of a fusible metal body positioned between and connecting the terminal sections; a fused section formed in a central section of the connection section, the fused section being smaller in cross section than other portions of the connection section, and a first and second low-melting-point metal pieces, each having an outer size identical or similar to the width of the connection section, the first low-melting-point metal piece is deposited on the front surface of the connection section such that the first low-melting-point metal piece partially traverses an edge of the fused section or is adjacent to an edge of the fused section but does not traverse to the edge of the fused section, and the second low-melting-point metal piece is deposited on a rear surface of the connection section such that the second low-melting-point metal piece partially traverses an edge of the fused section or is adjacent to an edge of the fused section but does not traverse to the edge of the fused section, wherein: the terminal sections and the connection section are made of the same metal base material that is zinc or a zinc alloy, and the first and second low-melting point pieces are located at symmetrical positions on the blade fuse with respect to the center of the fused section.
