To provide an exhaust structure of an electric vehicle which can eliminate an incongruity at a foot of an occupant caused by a hot airflow irrespective of a drive state.SOLUTION: In an exhaust structure of an electric vehicle V which comprises a chargeable/dischargeable battery module 20, an engine 61 and a fuel tank T which can store the fuel of the engine 61, and in which the engine 61 is not operated until the holding power of the battery module 20 is lowered beyond a prescribed threshold, the exhaust structure has an exhaust pipe 65 for exhausting exhaust emission from the engine 61, and air mixture means 68 arranged at a downstream end portion of the exhaust pipe 65. The air mixture means 68 comprises a progress direction guide part 68a for guiding a progress direction of an exhaust gas toward a lower part, a rear-descending shaped main body part 68b and a flat opening part 68c extending to a vehicle width direction. The exhaust structure is constituted so as to be capable of introducing atmospheric air at the surroundings from the flat opening part 68c.SELECTED DRAWING: Figure 11
