Disclosed is a thermoplastic molded product comprising a decorative material which has excellent shock resistance and flexural rigidity and thus can be used as a substitute for a window glass, a partition, a decorative panel or the like. The thermoplastic molded product comprises: a copolyester resin sheet; and one or more decorative materials laminated on the copolyester resin sheet, wherein said lamination is performed by applying heat and pressure to the copolyester resin sheet and decorative materials, and wherein said copolyester resin sheet is made from a copolyester resin having a structure in that an acid ingredient containing terephthalic acid is copolymerized with a diol ingredient containing 5 to 99 mol% of 1,4-cyclohexane dimethanol and 1 to 60 mol% of isosorbide, with respect to the total diol ingredients, and an acid moiety derived from the acid ingredient and an diol moiety derived from the diol ingredient are repeated.
