ABSTRACT:
A fuse comprises a housing formed of synthetic resin, and the housing including a peripheral wall having an upper opening, a fuse-element, which is melted by an excessive electrical current flowing therethrough, fixedly disposed in the housing and at least an air passage communicating between the inside and outside of the housing and formed on the wall portion of the housing. A heated air in the housing heated by heat generated in the fuse-element is discharged from the air passage, thereby it is prevented that the inside of the housing becomes high-temperature.
