The present invention provides a laminated film and a nonaqueous electrolyte secondary battery. The laminated film is a laminated film in which a porous film having a shutdown function, a heat-resistant porous layer containing plate-shaped inorganic particles and a binder, and a protective porous layer are sequentially contacted and laminated. The nonaqueous electrolyte secondary battery is a nonaqueous electrolyte secondary battery having a positive electrode, a negative electrode, a separator disposed between the positive electrode and the negative electrode, and an electrolyte, wherein the separator is the above-mentioned laminated film. |
