Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a transparent multilayer sheet having high flexibility and excellent in surface hardness and thermoforming property, through using polycarbonate having a specific structure as a core layer.SOLUTION: In a transparent multilayer sheet, a resin layer including an acrylic resin is laminated on one or both surfaces of a substrate layer including a polycarbonate resin. The polycarbonate resin includes a constitutional unit expressed by a following formula [1] (where R is an alkylene group having 1-6 carbon atoms, an arylene group having 6-10 carbon atoms or a cyclic alkylene group having 3-8 carbon atoms, of a single bond, and X and Y independently represent an alkyl group having 1-6 carbon atoms).
