PROBLEM TO BE SOLVED: To solve the inconvenience that a manual operation. type of fire extinguisher can not jet in the case when it is placed close to the origin of fire or its user is upset, an automatic type requires a power source and cannot be used in the case when power transmission is stopped or batteries are exhausted, or a pressure-accumulating type does got jet due to gas leakage when used. SOLUTION: This device has a container 1, an unsealing device 2 and a sensor 3. The container has filler 12 and pressurized gas 13 filled in the main body 11, and an opening 14 of the main body is sealed by welding a sealing plate 15. The unsealing device has a cylinder 21 and a piston 22, and the cylinder is detachable with the main body covered with the sealing plate. The cylinder is provided with a filler transmitting passage 23 that is the passage secured in a fitted state and a jet tube 24 connected with the transmitting passage 23, and the piston is slid to fit in the cylinder with a perforating needle 25 in one side toward the sealing plate. The sensor is a case 31 in which a gas- generating agent 32 is sealed, and it conducts to the cylinder through a conduit 33 to the face in the opposite side of the perforating needle of the piston.
