摘要： The present invention relates to a separator in which a porous polymer web layer of an ultrafine fiber and an electrolyte are swollen using an electro spinning method, and a non-porous film layer formed of a material through which electrolyte ions can be conducted is integrated with one surface or both surfaces of a positive electrode or a negative electrode to prevent the positive electrode and the negative electrode from being short-circuited with each other by inorganic particles contained in the polymer web even if the secondary battery is overheated, an electrode assembly and a secondary battery using the same, and a method for manufacturing the secondary battery. According to the present invention, the electrode assembly includes the positive electrode, the negative electrode, and the separator for separating the positive electrode and the negative electrode from each other, and the separator includes: a first non-porous polymer film layer; and the porous polymer web layer formed on the first non-porous polymer film layer and constituted by an ultrafine fiber formed of a mixture in which a heat-resistant polymer or the heat-resistant polymer and a swelling polymer are mixed with the inorganic particles.
