WIPO Patent Application WO/2021/215089
Kind Code:
A1
Abstract:
A heating implement (1) is equipped with a heat-generating body (3) comprising a powder of an oxidizable metal (3a), a powder of a carbon material (3b), and a powder of a porous substance (3c) excluding the oxidizable metal (3a) and the carbon material (3b). The heat-generating body (3) is a sheet-shaped object. For the heat-generating body (3), it is desirable that the mass ratio of the water content relative to the oxidizable metal (3a), multiplied by 100, amounts to a value falling between 30 and 270 inclusive. For the heat-generating body (3), it is desirable that the mass ratio of the porous substance (3c) content relative to the oxidizable metal (3a), multiplied by 100, amounts to a value falling between 1 and 30 inclusive. For the heat-generating body (3), it is desirable that the mass ratio of the porous substance (3c) content relative to the water, multiplied by 100, amounts to a value falling between 1 and 30 inclusive.
