ABSTRACT:
The present invention relates to a heat-conductive polyimide film comprising a heat-conductive powder dispersed therein with a concentration gradient. The film can be produced, for example, by centrifugal casting. The film can be used as an excellent component or member in those fields in which heat conductivity is required in addition to mechanical characteristics, heat resistance and chemical resistance. For example, it is used as a thermal fixation member in a laser printer.
