NOVELTY - The film has a binder polymer (2) selected from an inorganic particle and detritus. Packing factor of the inorganic particle and the detritus is selected in range of 60-70%. A displacing agent particle (1) is formed with a primary particle (3). The detritus is selected from polyethylene, polystyrene, polymethyl methacrylate, polyacetal, polyamide, polycarbonate, modified polyphenylene ether and polybutylene terephthalate.    USE - Organic-inorganic complex porous film for a separator of an electrochemical device i.e. lithium secondary battery, in an electrode structure of an electric vehicle and a power storage device e.g. cellular phone, camcorder and notebook computer (all claimed).    ADVANTAGE - The film improves packing factor of the inorganic particle and the detritus. The film applies heat to the inorganic particle and the primary particle, so that production efficiency of the film is improved. The film simplifies manufacturing process of the inorganic particle by dispersing the binder polymer into solvent, so that the film can be manufactured in a uniform manner.    DETAILED DESCRIPTION - The binder polymer is made of polyvinylidene fluoride-hexafluoro lochia propylene, polyvinylidene fluoride-trichloroethylene, polymethyl methacrylate, polyacrylonitrile, polyvinyl pyrrolidone, polyvinylacetate, ethylene-vinyl acetate copolymer, polyethylene oxide, cellulose acetate, cellulose acetate butylate, cellulose acetate propionate, cyanoethyl pullulan, cyanoethyl polyvinylalcohol, cyanoethylcellulose, cyanoethyl sucrose, pullulan, carboxyl methyl cellulose, acrylonitrile styrene butadiene copolymer or polyimide. INDEPENDENT CLAIMS are also included for the following:    (1) a method for manufacturing an organic-inorganic complex porous film    (2) an electrochemical device    (3) an electrode structure.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of an organic-inorganic complex porous film.    Displacing agent particle (1)    Binder polymer (2)    Primary particle (3)
