PURPOSE: An electrode assembly for a secondary battery is provided to reduce the winding number by half compared to the winding staring from the end portion, since a separator is wound from the center portion instead of the end portion. CONSTITUTION: An electrode assembly(200) comprises: a plurality of separator members(211a-211k) formed by winding a separator(210) starting from a central separator member that comprises a predetermined portion between the ends of the separator; and a plurality of first and second electrode members(220) positioned between each of the separator members, wherein the separator includes the plurality of separator members and the central separator member is one of the plurality of separator members, and wherein both opposite ends of the central separator member are curved in opposite directions, respectively.
