The purpose of the present invention is to provide a stable operating battery pack. Provided is the battery pack including a battery, a main switch, a control circuit, and a driving voltage supply unit. The battery includes at least one battery cell. The main switch is connected between a first node connected to the battery, and a second node connected to an external terminal. The control circuit manages the battery, and controls the main switch. The driving voltage supply unit generates driving voltage of the control unit by using voltage of a third node connected to each of the first and second nodes with a diode, and supplies the driving voltage to the control circuit. |
