<P>PROBLEM TO BE SOLVED: To provide a warming device having electromagnetic wave shielding performance and capable of shortening a current-carrying time with respect to a heating element such as an electrical blanket by the heat retaining performance. <P>SOLUTION: The warming device is provided with the heating element 300 generating heat by current-carrying and with a heat storage sheet 100 superposed on the heating element 300 and used. The heat storage sheet 100 has a bag body and water-containing gel sealed in the bag body. Since the heat storage sheet 100 is arranged, even if current-carrying to the heating element 300 is stopped, since warmth is maintained for a predetermined time, warming can be performed without being affected by electromagnetic waves and the current-carrying time can be shortened. <P>COPYRIGHT: (C)2010,JPO&INPIT |
