摘要： This invention can provide a stretched multilayer thermoplastic resin film comprising a layer including a thermoplastic resin (B) on at least one surface of a layer including a thermoplastic resin (A), the stretched multilayer thermoplastic resin film being characterized in that: the intrinsic birefringence of each of the thermoplastic resin (A) and the thermoplastic resin (B) is within a range from -0.005 to 0.005; the glass transition temperature of the thermoplastic resin (B) is 110°C or higher; and the saturated water absorption rate of the thermoplastic resin (B) is less than 1.1 wt%.
