PROBLEM TO BE SOLVED: To provide a polymer heating element having high durability, safety and chemical resistance, and to provide a method of manufacturing the polymer heating element. SOLUTION: A polymer heating element 1 comprises a pair of electrodes 3, sandwiched in between a base side resin film 2 and a cover side resin film 5, and a polymer resistor 4 formed between a pair of electrodes 3. The base-side resin film 2 and/or the cover-side resin film 5 consist of a resin component containing a thermoplastic polyester. The base-side resin film 2 and/or the cover-side resin film 5 consist of more than two different mutilayer structures. COPYRIGHT: (C)2007,JPO&INPIT |
