Abstract
The purpose of the present invention is to provide: a pellicle frame which is not susceptible to deterioration even if irradiated with short-wavelength light such as excimer light, and which is not susceptible to generation of an outgas or foreign substance; and a pellicle which uses this pellicle frame. In order to achieve the above-described purpose, this pellicle frame for supporting the outer periphery of a pellicle film is configured to comprise a frame and a film that is formed on the surface of the frame and contains a polyimide resin.
