<p><P>PROBLEM TO BE SOLVED: To provide a heating compact showing a sign of a replacement time by quickly lowering a temperature from a heating maximum temperature to the heating end and giving superior actual warm sensation and hyperthermia effect by gradually increasing a heating temperature. <P>SOLUTION: This heating compact is formed by including electrolyte and water in a heating intermediate compact including oxidizable metal, water retaining agent, and fibrous materials. The ratio of the content of the oxidizable metal to that of the water retaining agent in the heating compact is 45:1-0.3:1 (weight ratio), the total content rate of the oxidizable metal to the water retaining agent in the heating compact is 50-98 wt.%, a temperature lowering speed in five minutes from a time of reaching the heating maximum temperature of the heating compact to heating end is 0.7-10°C/5 min. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
