The secondary battery according to the present invention has the effect of preventing the breakage of the electrode leads due to the movement of the electrode assembly when external forces, such as small vibrations and dropping, are applied to the secondary battery, and, preferably, easily bending the electrode leads such that the PCM is mounted to the secondary battery.
