PROBLEM TO BE SOLVED: To provide a laminated molded body low in the coefficient of linear expansion, excellent in lightweight properties, impact resistance, durability, workability, productivity, etc., and especially preferably usable as an external building material such as an eaves trough or the like. SOLUTION: A thermoplastic polyester resin sheet in an amorphous state is drawn and stretched at a temperature from the glass transition temperature of a thermoplastic polyester resin -20°C to the glass transition temperature of the thermoplastic polyester resin +20°C and subsequently is uniaxially stretched at a temperature higher than the drawing and stretching temperature to obtain a stretched thermoplastic polyester resin sheet. Thermoplastic resin sheets are laminated/fused to both surfaces of the stretched thermoplastic polyester resin sheet through the stretched thermoplastic polyester resin sheet and a woven fabric and/or a nonwoven fabric of which the melting point is higher than that of the thermoplastic resin sheet to obtain the laminated molded body.
