PROBLEM TO BE SOLVED: To provide an exhaust structure of an electric vehicle capable of controlling pressure in a cabin without increasing a temperature in the cabin, and capable of exhausting air to the outside of the vehicle which is used to cool a battery and changed into hot air or air used to heat the battery and changed into cool air.SOLUTION: The exhaust structure includes an exhaust passage (4) making a battery (2) communicate with an exhaust duct (3). The exhaust duct (3) is in a box shape having a cross sectional area increasing from one side (3a) to the other side (3b) on an opposite face. In the exhaust duct (3), the exhaust passage (4) is connected so as to communicate with a lower part of one side (3a); an exhaust port (3b) is formed opened at the other side (3b) on the opposite face; and an inside air exhaust port (3d) is formed in an upper part of the other side (3c) adjoining to the one side (3a), the inside air exhaust port having a flap (3e) and forming an inside air merging region to exhaust air in the cabin to the exhaust duct. The exhaust duct (3) is disposed on a rear side face of a vehicle (1) so as to make the exhaust port (3b) communicate with the outside of the cabin.
