<P>PROBLEM TO BE SOLVED: To provide an imbalance reduction circuit, a power supply unit and an imbalance reduction method capable of reducing the possibility that the deterioration in a power accumulating element progressing in deterioration is accelerated due to uniformity of terminal voltage. Ž<P>SOLUTION: The imbalance reduction circuit includes: a voltage detecting section 320 for detecting each of terminal voltages V1-VN in power accumulating bodies B1-BN; a target voltage setting section 334 for setting each of target voltages Vtg1-VtgN corresponding to the power accumulating bodies respectively so that the lower the terminal voltage V1-VN detected by the voltage detecting section 320 are, the higher values of the target voltages Vtg1-VtgN are; and a discharging section 310 for executing discharging processing to discharge the power accumulating bodies B1-BN so that the terminal voltages V1-VN each become the target voltages Vtg1-VtgN set corresponding to the power accumulating bodies.
