Beschreibung
Zusammenfassung:	The present invention is able to provide a stretched multilayer thermoplastic resin film which comprises layers containing a thermoplastic resin (B) on both surfaces of a layer that contains a thermoplastic resin (A) and elastic particles, and wherein: respective intrinsic birefringences of the thermoplastic resin (A) and the thermoplastic resin (B) are within the range of from -0.005 to 0.005; the content ratio of the elastic particles in the whole layer containing the thermoplastic resin (A) and the elastic particles is 5-40% by weight; the glass transition temperature of the thermoplastic resin (B) is 110°C or higher; and the saturation water absorption of the thermoplastic resin (B) is less than 1.1 wt%.
