PROBLEM TO BE SOLVED: To provide a warmer which uses a linear and flexible exothermic body having PTC (positive temperature coefficient) characteristic as a heating source, and is applied to a diseased or desired site of a human body to warm the part.SOLUTION: The warmer includes: an exothermic body used as a heating source; and a coating film body comprising an inner film and an outer film to envelope the heating source, wherein the exothermic body emits a far-infrared ray having a peak wavelength between 6-10 μm and has PTC characteristic; the inner film is made of cloth which can keep the flexibility for protecting the heating source and transmits the far-infrared ray; and the outer film is made of cloth which can keep the flexibility and is napped for pleasant touch feeling. |
