PROBLEM TO BE SOLVED: To provide a polycarbonate molded product, in which the surface is protected with cured coat capable of imparting high weather resistance, and endurance to environmental change and high-temperature environment are improved, excellent in abrasion resistance and hot water resistance. SOLUTION: In a method for forming a coated polycarbonate sheet-like molded product composed of a polycarbonate sheet-like molded product, a primer layer provided at least on one side and a hard coat layer further provided thereon, the hard coat layer is formed by applying a hard coat liquid comprising (D) colloidal silica and (E) a hydrolytic condensation product of a trialkoxysilane represented by formula (1) (wherein R<SP>3</SP>is a 1-3C alkyl group substituted with one or more groups selected from the group consisting of a 1-4C alkyl group, a vinyl group or methacryloxy group, an amino group, a glycidoxy group and 3,4-epoxycyclohexyl group; R<SP>4</SP>is a 1-4C alkyl group) and thermally curing the hard coat liquid in an atmosphere of humidity of 14-16 g/kg.
