Abstract

The purpose of the present invention is to provide a separator for a secondary cell in which organic resin microparticles are laminated at low cost and adhesiveness with respect to an electrode is produced. The present invention is a separator for a secondary cell characterized in that a porous layer containing organic resin microparticles having an average grain diameter of 0. 02 ?m to less than 0.40 ?m is laminated on at least one surface of a porous base material, the film thickness of the porous layer being 0.10 ?m to less than 2.5 ?m.
