A capacity indicating device is configured to indicate a fully charged state when full recharging has been conducted even if the battery is degraded; hold the possible traveling distance per segment roughly constant; and make it easy to estimate the possible cruising distance. The capacity indicating device has an indication control unit that: (1) allocates a prescribed portion of the battery capacity of a vehicle to a capacity adjustment region that serves to adjust the battery capacity as it decreases due to degradation of the battery; (2) calculates the degradation degree of the battery based on the detected voltage value and current value; (3) corrects the capacity adjustment region a based on the calculated degradation degree; and (4) indicates the present battery capacity using segments that are not affected by the degradation of the battery.
