摘要

An exothermic device has an exothermic composition enclosed in a flat pouch formed of film or sheet, at least one surface thereof being gas-permeable. The exothermic composition comprises a laminate of an exothermic reaction layer having an exothermic substance as an essential ingredient thereof, and a single or a plurality of reaction auxiliary layer(s) including other ingredients. The exothermic device is incorporated into a sticking pad applicable to the human body to provide a warming and/or therapeutic effect.
