Member made from the production method and the method of the curved member having a high quality design surface

An object of the present invention is used in glazing member of transport such as automobiles, to provide a process which can be manufactured at a low cost a curved member with respect to various kinds with a high quality design surface. The present invention prepares a sheet having a high quality design surface was injection compression molding a resin material containing (1) a thermoplastic resin, (2) when the glass transition temperature of the resin material was Tg (℃), (Tg + 5) ~ (Tg + 70) sheets preheated to soften at ° C. temperature, (3) by the action of pressure to bend the high-quality design surface to the softened sheet, Comprising the steps a method of manufacturing a curved element having a high-quality design surface.
