<P>PROBLEM TO BE SOLVED: To provide a planar heat generating body having high energy efficiency. <P>SOLUTION: A heat generating layer is formed by applying a coating composition with a mixture of a ferritic inorganic granular substance or a crushed material thereof and a carbon powder and/or carbon fiber dispersed in a synthetic resin emulsion or synthetic resin solution to the surface of a substrate, and then drying. The heat generating layer generates heat according to Joule's law, and the ferritic inorganic granular substance also generates heat by absorbing electromagnetic wave simultaneously generated by energization. In addition, the heat generating layer efficiently radiates infrared rays, serving as a planar heat generating body of high energy efficiency. <P>COPYRIGHT: (C)2009,JPO&INPIT |
