A new kind of pellicle frame is proposed which is made up of a core body and a clad body; the core body consists of a composite of carbon fiber plus resin, and it is preferred that the carbon fiber exists in the form of a laminated body of carbon fiber sheets in which the resin is impregnated; and the clad body is the outer layer sealing the core body such that no carbon is exposed through the clad body.
