Abstract (en)

[origin: JPS6431369A] PURPOSE: To provide a flat heating plate with high-temperature load characteristic for preventing the clouding of a mirror glass with a simple manufacturing method by forming at least a part of a heating unit, having a heating resistance installed by coating by partially use of a paper-like base. CONSTITUTION: An object 10 to be heated, such as a mirror is exposed constantly to a high humidity which causes clouding in a bathroom, and a heating device having a heating resistance 2 on the reverse side are arranged. The surface of a support body 3 for housing the heating resistance 2 covers the object 10 to be heated, so as to airtightly prevent moisture by use of a thin self-adhesive layer 14 or a layer similar to the support body. The heating resistance 2 is formed of a mixture of a paste mainly containing a metal and a graphite paste, and stabilized by thermal treatment, bonded and hardened with the support body 3. According to such a structure, despite the simple manufacturing process a flat heating plate for preventing the clouding of a mirror glass which has high-temperature load characteristic can be provided.
