1. A cable-type battery, comprising:
a cable-type battery cell including an internal electrode including at least one internal electrode layer having an internal electrode active material formed on a surface of an internal current collector extending in a longitudinal direction to have a cross section of a preset shape, a separation layer formed to surround the at least one internal electrode layer, and an external electrode including an external electrode layer formed to surround the separation layer and having an external electrode active material formed on a surface of an external current collector; and
a protection circuit module electrically connected to the battery cell to protect the battery cell, wherein wires respectively connected to the internal electrode and the external electrode are formed at one end of the protection circuit module or are respectively formed at opposing ends of the protection circuit module,
wherein the protection circuit module includes an accommodating protection circuit module,
wherein the accommodating protection circuit module is provided to accommodate the battery cell,
wherein the accommodating protection circuit module is provided as a flexible board to surround a periphery of the battery cell, and
wherein a circuit component is mounted between the accommodating protection circuit module and the battery cell to an inside of the accommodating protection circuit module.
