There is provided an apparatus for evaluating a capacitor, including: a charge/discharge control unit 100 that controls charge and discharge, a charge/discharge switch 200 that selects a connection between a capacitor CSP to be measured and a power supply unit 50 or a connection between the capacitor CSP and a discharge path DP, a discharge unit 300 that is connected to the discharge path DP and provides discharge resistance for the discharge of the capacitor CSP, a voltage measuring unit 400 that measures the voltage of the capacitor CSP, a current measuring unit 500 that measures the charge current or discharge current of the capacitor CSP, and a main control unit 600 that controls the charge and discharge through the charge/discharge control unit 100 and obtains equivalent series resistance Res, capacitance C and self discharge resistance Rsd during the charge and discharge.
