ABSTRACT:
A heat-resistant insulation sheet 40 is formed from an insulation base 41 divided into an insulation region Z, a heat-generating region Y, and a pressing region X. The insulation base 41 is formed from a polyimide resin film member. A rectangular-shaped electrically-conductive resilient body 46 is attached on the pressing region X and a resistance-type heat-generating body 44 is attached on the heat-generating region Y. The resilient body 46 and the heat-generating body 44 are formed integrally from the same stainless steel plate, which is attached on the surface of the insulation base 41 and etched into a desired pattern. The heat-resistant insulation sheet 40 formed in this manner is mounted into a roller body in a rolled up condition with the pressing region X disposed interior to the heat-generating region Y, and the heat-generating region Y disposed interior to the insulation region Z.
