Abstract: A battery pack comprises a battery and a flexible printed circuit board (FPC) utilized to detect a voltage and a temperature of the battery. The FPC comprises a substrate having a front surface and a back surface, a thermistor which detects a temperature of the battery, temperature detection lines and voltage detection lines. The temperature detection lines are electrically connected to a thermistor and arranged between the back surface and the battery. The voltage detection lines are arranged on the front surface so as to overlap the temperature detection lines in a case that the FPC is observed in a plane view in a transmissive manner from a back surface to a front surface.

Abstract: The battery pack includes a base having a heat dissipation wall, a switching device for controlling current having a plurality of electrode terminals, being disposed so as to be capable of transferring released heat to the heat dissipation wall, and a bus bar having a connection terminal that is connected to the switching device or a unit cell so as to enable energization. The connection terminal is disposed so as to be positioned in an area corresponding to a width of the switching device in a direction in which the electrode terminals are arranged in line and in an area extending to a periphery of the switching device in a direction orthogonal to the direction in which the electrode terminals are arranged in line.
