The utility model discloses an anti-explosion short-circuit-prevention capacitor, comprising a film core, a leading-out terminal and a shell for wrapping the film core and the leading-out terminal, wherein the shell is also internally provided with a colloid package filled with curing adhesives which can be cured when meeting light or air and have an insulating effect. According to the anti-explosion short-circuit-prevention capacitor, when the anti-explosion short-circuit-prevention capacitor explodes, the colloid package cracks, and the curing adhesives in the colloid package are scattered over the surfaces of the anti-explosion short-circuit-prevention capacitor and surroundings thereof, so that an insulating layer is formed on the surface of an exposed circuit conductor, and the probability of short circuiting of a circuit is effectively reduced.
