An electrode assembly is provided to prevent damages of an electrode assembly with reducing short circuit induction probability of the secondary battery by forming a ceramic coating layer with uniform thickness on an electrode. An electrode assembly comprises a positive electrode(210) having a positive electrode active material layer(213); a negative electrode(220) having a negative active material layer(223); and a ceramic coating layer(215) formed on at least one side of among sides facing each other. The ceramic coating layer comprises ceramic powder and binder. The specific surface area of the ceramic powder is formed with more than 1.5 m^2/g and less than 15.0 m^2/g. |
