PURPOSE: A secondary battery is provided to maintain stable capacity by uniformly maintaining the interface of an electrode group and to stably insulate the electrode group and the case by easily insulating an insulating member at a position between the electrode group and the case. CONSTITUTION: A secondary battery(100) includes: an electrode group(15) including a separator in which a positive electrode, a negative electrode, and a separator positioned between the positive and negative electrodes; a case(14) in which the electrode group is built in; terminals(21,22) which are electrically connected the electrode group; and an insulating member(30) which is located between the electrode group and the case and includes a base(31) and four insulating plates(32,34,36,38) extended from the base. |
