An electric vehicle comprising: a front wheel; an electric motor that is configured to drive the front wheel; a battery that is configured to supply electrical power to the electric motor; a rear wheel; a metallic frame that is configured to support the front wheel and the rear wheel, a vehicle-cabin forming portion that includes a floor having a floor surface of a vehicle cabin and a peripheral wall that is connected to a peripheral portion of the floor so as to extend upwards from the floor and to surround the floor along the peripheral portion of the floor; and outer plates, wherein, the metallic frame has a plurality of pillars (14L, 14R, 15L, 15R, 16L, 16R): left and right front pillars (14L, 14R), left and right center pillars (15L, 15R) and left and right rear pillars (16L, 16R); and a plurality of roof bars, and a plurality of front bars, the plurality of roof bars respectively connects upper ends of the pillars (14L, 14R, 15L, 15R, 16L, 16R), the vehicle-cabin forming portion is supported inside the metallic frame, the outer plates are supported by the plurality of pillars (14L, 14R, 15L, 15R, 16L, 16R) and the plurality of roof bars, and cover the vehicle cabin, the peripheral wall forms a subject aperture that is at least a lower-side portion of an aperture used for accesses of a passenger, the electric vehicle further comprises a door member that is capable of closing/opening the subject aperture, and the vehicle-cabin forming portion and the door member form a cup-shaped member (30, 81L) in the state in which the door member is closed, the cup-shaped member (30, 81L) being configured to be able to provide the electric vehicle with buoyancy sufficient to allow the electric vehicle to float on the water surface, when the front wheel, the electric motor, the rear wheel, and the battery are projected in a direction parallel to a left-right direction of the electric vehicle: the electric motor is arranged at a position at which at least a part of the electric motor overlaps with the front wheel; the battery is arranged at a position at which at least a part of the battery overlaps with the rear wheel; and a center of gravity (911, 912) of the electric vehicle is placed below a waterline (901, 902) in both a light load state and a full load state, and at the same time, a position of the center of gravity (911, 912) in a forward-to-backward direction of the electric vehicle is placed between the front wheel and the rear wheel. a front wheel;
