To provide a life-saving warming tool stored in a life-saving tool such as a life jacket and capable of contacting with sea water or fresh water when encountering an unexpected sea accident or a drowning accident, allowing immediate entry of water such as sea water into a sealed bag body from an inlet, generating exothermic reaction through contact between an exothermic agent and water, transmitting heat generated through the exothermic reaction to a sufferer, enabling the sufferer to warm himself through heat transmission, convection, and heat radiation, enabling the sufferer to warm the heart, hands and legs, head and the like of the body by means of the life-saving warming tool, and thus providing effective measures against sea accidents or the like.SOLUTION: This life-saving warming tool is stored in a life-saving tool such as a life jacket W, and comprises: an exothermic agent that causes exothermic reaction through contact with water; a water absorption sheet for enveloping the exothermic agent; and a sealed bag body F for sealing the water absorption sheet enveloping the exothermic agent. An inlet is formed in the sealed bag body.SELECTED DRAWING: Figure 7
