The purpose of the present invention is to provide a process for manufacturing a plastic sheet, said process being capable of improving the strength and breaking elongation (elongation rate) of a raw material plastic sheet having a high filler content, and thereby improving the tolerance of processing conditions. A process for manufacturing a plastic sheet which includes a bending step comprising: bringing, in the course of transferring a raw material plastic sheet that contains a filler in an amount of 50 to 85mass% in the flow direction, the raw material plastic sheet into contact with the surface of a solid object in such a way that the sheet is pushed against the surface of the solid object; thereby making the sheet bent in the contact zone, and generating a stress that affects the inside of the sheet; and thus treating the sheet. |
