LAMINATED FILM, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

The present invention provides a laminated film and a non-aqueous electrolyte secondary battery. The laminated film has a structure in which a porous film having a shutdown function, a heat resistant porous layer containing plate-like inorganic particles and a binder, and a protective porous layer are stacked on each other in this order. The non-aqueous electrolyte secondary battery comprises 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.
