PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating coil which has high heating efficiency, is capable of shortening of warm-up time and of quick start as well as power saving. SOLUTION: An adhesive A105 is plotted in the shape of closed curve around the region where an EL element 102 is and, further, an adhesive B105 is plotted in the shape of closed curve around the adhesive A. A hygroscopic matter 106 is dispersed between the adhesive A and the adhesive B. With this construction, water passing through the adhesive B passes through a space where a hygroscopic matter 104 is dispersed before it enters an airtight space containing the EL element, so that it is likely to be absorbed there. Thus, water entering the airtight space where the EL element is can be reduced in amount. |
