A sprinkler having a triggering head assembly using a film heater is provided to heat a heat sensitive body to make it decomposed promptly and to be operated normally even if it is used for a long period of time. A sprinkler having a triggering head assembly using a film heater includes a head body, a heat sensitive body, an intercepting unit, a film heater(112), a power supply unit(130), a fire sensing device(140) and a controller(150). The head body includes a discharge hole for discharging compressed fire extinguishing liquid to the outside. The heat sensitive body is decomposed when the temperature goes up to a predetermined level. The intercepting unit intercepts the discharge hole by being supported by the heat sensitive body, and release the interception of the discharge hole when the heat sensitive body is decomposed.
