An electrode assembly (10) and a secondary battery having the same are provided. More particularly, an electrode assembly (10) which can improve efficiency and stability of a battery, and a secondary battery having the same are provided. The electrode assembly (10) includes: a positive electrode plate (20) having a positive electrode collector (21), and a positive electrode coated portion (22) and a positive electrode non-coated portion (23) formed on the positive electrode collector (21); a negative electrode plate (30) having a negative electrode collector (31), and a negative electrode coated portion (32) and a negative electrode non-coated portion (33) formed on the negative electrode collector (31); a separator (40) interposed between the positive electrode plate (20) and the negative electrode plate (30); and an insulating member (26,36) disposed on one side of the positive or negative electrode non-coated portion (23,33), and formed adjacent to at least one of both ends of the positive electrode coating portion (22) or the negative electrode coating portion (32). |
