A secondary battery with a protection circuit module having one of a hole and a groove containg a current interrupting device for compensating for the thickness of the PTC, so that an overall length of the secondary battery can be reduced. The current interrupting device may be a PTC, the PTC comprises an upper electrode, a main body and a lower electrode, and the upper electrode, the main body and the lower electrode may be sequentially disposed in a vertical position. Moreover, the PTC comprises a first electrode, a main body and a second electrode, and the first electrode, main body and second electrode may be sequentially disposed along a horizontal line. |
