Abstract

A method for manufacturing a polyimide sleeve where a polyimide sleeve of a high quality can be manufactured easily with a superior yield. A sleeve of a release resin is fitted on a planished metal core or a core at least whose outer surface is made of a release resin, and a polyimide precursor solution is applied on its outer surface. Next, after generating an imide reaction of the polyimide precursor by heating to form an almost completely cured polyimide sleeve, this polyimide sleeve is removed from the core together with the sleeve of the release resin. Furthermore, the polyimide sleeve is separated from the sleeve of the release resin.
