Abstract: Provided are an electrode plate and a secondary battery having the same. The electrode plate comprises a current collector and an active material layer, wherein the current collector comprises a main body portion and tabs, the active material layer is coated on the surface of the main body portion, and the tabs extend from one end of the main body portion along the first direction; a first insulating portion is formed on the end face of the main body portion that is provided with the tabs, and a second insulating portion different from the first insulating portion is formed on the end faces of the main body portion that are not provided with the tabs. The electrode plate of the present application has a good end-face insulation protection and can improve the safety performance of the secondary battery.
