PROBLEM TO BE SOLVED: To provide a laminated white film having high interface adhesive properties in a lamination between a thermoplastic white film and a heat- resistant resin layer, and having good flatness, heat resistance, whiteness, printing properties, and productivity. SOLUTION: The laminated white film is composed by laminating the heat- resistant resin layer having a heat-resistant layer, which is soluble in a dipolar aprotic solvent, as a main component on at least one side of a biaxially oriented thermoplastic white film. The heat-resistant resin layer is directly laminated on the thermoplastic white film substantially with no adhering layer therebetween. And the laminated white film is at least monoaxially stretched after applying a coating liquid wherein the heat-resistant resin is solved in the dipolar aprotic solvent.
