A charge/discharge current detection circuit includes a detection resistance that converts a charge current and a discharge current to a detection voltage, a level shifter circuit that level-shifts the detection voltage by a predetermined value, and an amplifier circuit that amplifies an output voltage of the level shifter circuit and outputs the amplified output voltage of the level shifter circuit. The level shifter circuit applies to the detection voltage a predetermined divided voltage obtained by resistance-dividing a reference voltage, to thereby level-shift the detection voltage.
