PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate porous film suppressed in the generation of a streak-like recess on a filler layer surface.SOLUTION: The method for manufacturing a laminate porous film is a method for manufacturing a laminate porous film having a filler layer containing inorganic particles as the main constituent on one surface of a porous base material layer containing polyolefin as the main constituent, and a resin layer containing resin particles as the main constituent on the other surface. The method includes: coating a coating liquid having a content ratio of more than 50 wt.% of inorganic particles in the whole volume of the components excluding a medium, on one surface of the porous base material layer; drying the product to form the filler layer; coating a coating liquid having a content ratio of more than 50 wt.% of resin particles in the whole volume of the components excluding a medium, on the other surface of the porous base material layer; and drying the product to form the resin layer. |
