PURPOSE: A battery pack is provided to quickly transfer heat generated inside a battery pack to a positive temperature element, thereby quickly blocking current even in case the temperature of the battery cell is increased. CONSTITUTION: A battery pack comprises: a battery cell with a cell taps; a protective circuit module comprising an internal terminal(124) connected with the cell tap, a positive temperature element connecting to the internal terminal, and a wiring pattern(128) electrically connecting the internal terminal and the positive temperature element, arranged between the internal terminal and the positive temperature element, and a heat transfer element contacted with the wiring pattern by one side, and in which both sides are connected to the internal terminal and the positive temperature element. The battery cell is pouch type. The heat transfer element is formed from a thermoconductive acryl foam tape. |
