In a balance correction circuit 1 including a plurality of converter type balance correction units that control a supply of a current to a plurality of power storage cells by complementarily on/off controlling two switching elements and hereby allowing to exchange power between or among power storage cells via an inductor to equalize the voltages of the power storage cells, a common timing signal used to generate a control signal of a switching element is supplied to each of the above balance correction units. For example, the balance correction circuit 1 generates a timing signal to supply to a first balance correction unit based on a variation in a voltage applied to the capacitive element charged by a voltage difference created between a control signal generated by the second balance correction unit and a second power storage cell cathode of the balance correction unit.
