PROBLEM TO BE SOLVED: To provide an extinguishing chemicals tank for an automatic extinguishing system of a building. SOLUTION: This extinguishing chemicals tank is filled with the N<SB>2</SB>gas in the high-pressure condition over the extinguishing chemicals filled inside. When a fire is sensed, a N<SB>2</SB>tank and an extinguishing chemicals tank are opened, and during the time when the N<SB>2</SB>gas is thrown from the N<SB>2</SB>tank into the extinguishing chemicals tank, since the extinguishing chemicals already filled in the extinguishing chemicals tank is pressurized by the N<SB>2</SB>gas filled in the extinguishing chemicals tank, the extinguishing chemicals is discharged quickly by the pressurization to extinguish a fire in an early stage.
