This fire extinguishing agent comprises: a carboxylic acid alkali metal salt comprising one or two or more selected from among potassium acetate, potassium citrate, sodium acetate, and sodium citrate;a natural surfactant comprising one or two or more selected from among a lecithin, a saponin, and a casein; and water, wherein 30-55 g of the carboxylic acid alkali metal salt and 0.107-0.200 g of the natural surfactant are contained in a total amount of 100 milliliters of the fire extinguishing agent, and the content ratio of the carboxylic acid alkali metal salt to the natural surfactant is 150:1-275:1 (the carboxylic acid alkali metal salt:the natural surfactant) by mass. Accordingly, the fire extinguishing agent exhibits excellent fire extinguishing performance while also being highly safe for the human body, and uses a reduced amount of natural surfactant. 本发明涉及如下所述的灭火剂：由选自乙酸钾、柠檬酸钾、乙酸钠以及柠檬酸钠的1种或2种以上构成的羧酸碱金属盐；与由选自卵磷脂、皂角苷以及酪蛋白的1种或2种以上构成的天然表面活性剂；与水构成，在总量100毫升中，以羧酸碱金属盐30～55g、天然表面活性剂0.107～0.200g的比例含有羧酸碱金属盐与天然表面活性
