PROBLEM TO BE SOLVED: To provide an apparatus for molding a supercritical plastic material, etc., which enables the observation of the shearing and molding states of a specimen in a supercritical state. SOLUTION: The apparatus for molding a plastic film, fibers, and a nonwoven fabric which are in supercritical states is composed of a shearing tank having a shearing mechanism which is rotated by a motor and changes a shear rate freely and a molding tank having one or more specimen rolling roller mechanisms facing each other. The shearing tank and the molding tank are mutually partitioned through a heat-insulating material penetrated approximately to the center part by a specimen discharge nozzle for discharging the specimen from the shearing tank to the molding tank. Observation windows for visualizing the insides of the shearing and molding tanks which are installed on the sides of the tanks are composed of press parts, washers, window members, and annular sealing packings, respectively.
