The present invention provides a laminated film and a non-aqueous electrolyte secondary battery. The laminated film is a laminated film in which a porous film having a shutdown function, a heat resistant porous layer consisting of an inorganic filler and a binder, and a protective porous layer are stacked on each other in this order. The non-aqueous electrolyte secondary battery is a non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode, a separator located between the positive electrode and the negative electrode, and an electrolyte, wherein the separator is the above-mentioned laminated film.
