1. A reachable range calculation apparatus for computing a range that a vehicle traveling on stored energy is able to reach, comprising:

  • a storage part stores beforehand information on a required amount of energy consumed when the vehicle moves, by using each of a plurality of areas into which a map has been divided as a unit;

    an integration part integrates, with respect to movement of the vehicle from a specified origin to a surrounding area, a required amount of energy on the basis of the required amount of energy stored in the storage part, by adding a required amount of energy of an area each time the vehicle moves between areas; and

    a range determination part determines, on the basis of an amount of remaining energy in a battery mounted in the vehicle and an integrated required amount of energy obtained by the integration part integrating energy-consumption amounts, a reachable range, which is a range of areas that the vehicle is able to reach using the amount of remaining energy.
