Abstract: Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.
