Conventionally, a main fuse resistor is a Ni-P formed by an electroless plating method as a fuse resistance film.
Alternatively, an alloy thereof, Ag, a low melting point Sn—Pb, etc. is used, and the resistance film self-heats when an electric current flows,
The resistance film has a mechanism of fusing at the melting point or higher. A fuse resistance film is also known, which has a mechanism in which an insulating film that melts at a low temperature is provided in a part of the lower portion of the fuse resistance film, and the resistance film generates heat to melt the insulating film.

On the other hand, a protective coat film is usually formed on the resistance film of the fuse resistor, and the resistance film described above is also coated with, for example, an epoxy resin film.
The epoxy resin film generates a small amount of smoke and carbonizes when the fuse is blown, the carbonized portion becomes conductive, a weak current is passed, and the fusing time of the resistance film is lengthened. Therefore, it is conceivable to use a high melting point inorganic material such as glass as the protective coat film, but when using the above fuse resistance film,
Since the resistance film is formed by plating, vapor deposition, sputtering, etc., and the material itself has a low melting point, it is difficult to form a high melting point protective coat film of glass or the like which requires a temperature of 500 ° C. or higher for formation. Therefore, the actual situation is that an epoxy resin must be used.
