PROBLEM TO BE SOLVED: To provide a sprinkler head which operates stably, has excellent reliability and has a simple structure. SOLUTION: The sprinkler head 10 stops water W for fire-fighting by sealing a channel F by a sealing plate 16 during a normal situation. During a fire, heat caused by the fire is sensed by a heat-sensitive plate 26 and is transferred to a combustion agent 28 filled inside a combustion chamber 24. Accordingly, when the combustion agent 28 containing an automatic ignition component reaches or exceeds a predetermined temperature, the combustion agent 28 ignites, the sealing plate 16 is fractured by the explosion pressure or gas pressure and the channel F is unsealed.
