PROBLEM TO BE SOLVED: To provide a travelable distance calculation unit of an electric vehicle that travels using a power charged in a battery, the travelable distance calculation unit highly precisely calculating a travelable distance in consideration of a road wet situation. ! SOLUTION: There are included: mean electricity cost calculation means 25 that calculates a mean electricity cost representing a travelable distance per a unit capacity of a battery; basic travelable distance calculation means 27 that calculates a travelable distance on the basis of the mean electricity cost which is calculated by the mean electricity cost calculation means 25, and a remaining amount of electricity of the battery; road wet situation discrimination means 29 that discriminates a wet situation of a traveling road surface; and travelable distance correction means 31 that, when the road wet situation discrimination means 29 determines that a road surface is wet, corrects the travelable distance calculated by the basic t |
