Abstract

A resin sheet is manufactured by: forming a rapidly-cooled transparent polypropylene sheet by rapidly cooling a molten polypropylene resin; laminating on the rapidly-cooled transparent polypropylene sheet a resin layer of polyurethane resin, the polyurethane resin having a tensile-rupture elongation in a range from 150% to 900% and a softening point in a range from 50 degrees C. to 180 degrees C.; and laminating a print layer on the resin layer. A molded article having a non-planar molding made of the resin sheet is provided by insert molding. The molding is formed into a complicated shape where a part of the molding has: 150% or more of an elongation ratio; 0.8 or less of a film-thickness ratio (B/A) before and after the sheet is molded; and/or a surface area ratio (Y/X) before and after the sheet is molded in a range from 1.5 to 5.
