Battery pack
A battery pack includes a pouch-type bare cell, a protecting circuit module, a top case and a protecting circuit module support part. The pouch-type bare cell has a sealing region positioned in an extraction direction of an electrode lead. The protecting circuit module is positioned in the sealing region and connected to the electrode lead. The top case surrounds the protecting circuit module. The protecting circuit module support part is provided between the top case and the protecting circuit module. Accordingly, the protecting circuit module support part is formed between the top case and the protecting circuit module, so that it is possible to prevent a component mounted on the protecting circuit module from being damaged by an external impact and to prevent the inflow of a foreign matter from the outside of the battery pack, thereby improving the reliability and safety of the battery pack.
