A porous film comprising non-conductive particles and a graft polymer; a slurry for a porous film, which comprises non-conductive particles, a graft polymer and a solvent; and an electrode for a secondary battery, which comprises a current collector, an electrode mix layer adhered to the current collector and comprising a binder and an electrode active material, and the porous film laminated on the surface of the electrode mix layer. In the porous film, high dispersibility of the non-conductive particles and a proper level of electrolyte solution holding property can be achieved while keeping an effect of preventing the occurrence of electrical short and inhibiting thermal shrinkage at a high level, and a high high-temperature properties and high rate properties imparted as a result of the introduction of the porous film layer. |
