A secondary battery capable of being formed to be relatively small by reducing the sizes of internal devices and compactly locating the internal devices. Accordingly, the volume of the secondary battery is reduced and the capacity thereof is maintained, thereby increasing the capacity density of the secondary battery. In one embodiment, the secondary battery includes a bare cell having a cap plate and a protection circuit module on the bare cell and including a printed circuit board surface-contacting the cap plate.
