摘要

The purpose of the present invention is to produce a large-sized molded polyimide foam body, which can be used as a heat insulating material, a vibration absorbing material or a sound absorbing material, while suppressing the production cost and the production risk. Specifically disclosed is a self-adhesive polyimide foam which has self-adhesive properties. The self-adhesive polyimide foam can be curved. Consequently, by utilizing the self-adhesive polyimide foam, a molded polyimide foam body having a complicated shape can be easily obtained and a molded polyimide foam body having a uniform foaming ratio can be obtained.
