PROBLEM TO BE SOLVED: To provide an organic/inorganic composite porous film and an electrochemical element using the film.SOLUTION: The organic/inorganic composite porous film of the present invention contains (a) inorganic particles and (b) a binder polymer coating layer partially or wholly formed on surfaces of the inorganic particles, in which the inorganic particles are interconnected and fixed by the binder polymer and interstitial volumes among the inorganic particles form a microscale pore structure. The electrochemical element including the organic/inorganic composite porous film can simultaneously enhance safeness and performances. 【課題】有機／無機複合多孔性フィルム及びこれを用いる電気化学素子を提供すること。【解決手段】本発明に係る有機／無機複合多孔性フィルムは、（ａ）無機物粒子、及び（ｂ） 前記無機物粒子の表面の一部または全部に形成されたバインダー高分子コート層、を含み、前記バインダー高分子により無機物粒子同士が結び付いて固定され、前記無機物粒子間のインタースティシャル・ボリューム（interstitial volume）がマイクロ単位の気孔構造を形成することを特徴とする。本発明に係る有機／無機複合多孔性フィルムを備える電気化学素子は、安全性及び性能アップを同時に図ることができる。【選択図】図１
