PROBLEM TO BE SOLVED: To keep the body warm in a wide range and prevent lowering of heating value or stop of heating during use by connecting each one end of an air supply or exhaust passages to one or both of an intake port and an exhaust port provided in a heat source part, and extending the other end to the vicinity of the tip of a belt part and providing a projected part on the side of the belt part. SOLUTION: When clothing is worn on this warmer, exhaust discharged from the waist is about to enter the vicinity of a filter 15 of the front through the sides in the clothing. As a wall is formed by a projection 25 in the clothing, however, the exhaust is kept from entering the front. Further, as the exhaust is heavier than the air, it will not flow through the upper side of the projection 25. Thus, an air supply passage 14 is connected to an air supply port 12, and supply air and exhaust are separated from each other between the front of the human body and the back thereof, and as the projection 25 is provided between the supply air and the exhaust, exhaust discharged at the back of the human body is prevented from entering the tip of the air supply passage 14 in the front of the human body so that it is diffused at the back of the human body. Accordingly, incomplete combustion due to short-circuit can be prevented so as to always generate a stable value of heat.
