Abstract: A kit that includes an exothermic structure, at least two pressure-sensitive adhesive structures, and an air-impermeable bag is used to make an exothermic structure having at least two pressure-sensitive adhesive structures. The exothermic structure includes a pouch having an air-permeable side and an air-impermeable side, and an exothermic composition. The adhesive structures each comprise a base, an adhesive layer, and a cover in this order. To make the exothermic structure, parts of the covers are peeled off to expose parts of surfaces of the adhesive layers, and then the exposed adhesive layers are adhered to ends of the air-permeable side of the exothermic structure.
