PROBLEM TO BE SOLVED: To provide an exothermic body utilizing an exothermic composition generating heat by touching oxygen in the air which can easily and correctly control exothermic temperature (a heat generation characteristic). SOLUTION: (1) The exothermic composition is an exothermic body contained in a flat permeable bag in which a permeable packaging material, keeping an air hole bored by irradiation with a laser beam, is used for one side or both sides, (2) a sheet-like support body holding the exothermic composition within a vacant space is an exothermic body contained in a flat permeable bag in which a permeable packaging material, keeping the air hole bored by irradiation with the laser beam, is used for one side or both sides, and (3) two or more exothermic cells, in which each of the exothermic compositions is separately arranged, are exothermic bodies contained in the vacant space of the support body consisting of two sheets in which a permeable packaging material, keeping the air hole bored by irradiation with the laser beam, is used for one side or both sides.
