A hot compress structure comprising a flat bag having no opening and having one surface constituted by a gas-permeable film, and a heating composition capable of generating heat in the presence of air and sealed in the interior of the flat bag, with a compress layer being provided on the other surface side of the flat bag, the gas-permeable film having a moisture permeability of 100 to 400 g/m2.24 hr as measured according to an ASTM method (E-96-80D method). When this hot compress structure is brought into close contact with the human body, the heat generated from the heating composition is transferred to the whole skin surface of an affected part uniformly through the compress layer and a safe temperature not causing a low-temperature burn is maintained for a long time; besides, by the generation of heat, a local blood circulation is accelerated to improve a local metabolism.
