A charge-discharge control circuit includes a positive power-supply terminal; a negative power-supply terminal; a charge-discharge discrimination circuit which discriminates a discharging state in which a discharging current flows and a charging state in which a charging current flows based on a voltage at a charge-discharge path and a preset charge-discharge discrimination voltage; and a control circuit which turns on a discharge control FET and a charge control FET in a charge-inhibition state and the discharging state or turns off the charge control FET in the charge-inhibition state and the charging state.
