Abstract
The method for molding a resin reinforced with fiber wherein a resin sheet reinforced with fiber is positioned juxtaposed a face of a mold, which is either one of a female mold or a male mold, and then hardened, but before molding, modifying the viscosity to different levels in different portions of the resin sheet. Thus, it is possible to surely prevent occurrence of a partial difference in thickness of the moldings or, if necessary, to partially change these thicknesses according to predetermined values.
