PROBLEM TO BE SOLVED: To provide a door structure of an automobile which improves closing rigidity in closing a door without increasing the weight of the door by adjusting an inner panel to have different plate thickness so that each portion thereof has proper rigidity, adjusting the plate thickness of the rear side in the longitudinal direction of the vehicle to be larger than the plate thickness of intermediate parts so that the center of gravity of the door is placed on the side of the rear side more than the center in the longitudinal direction of the vehicle, and shifting the center of gravity of the door to the rear part far from the supporting point for opening/closing the door to increase rotating moment of the door. SOLUTION: The door structure of an automobile is formed by joining an outer panel and an inner panel 2. The front part 3 of the inner panel 2 in the longitudinal direction of the vehicle is connected to the vehicle body through hinges 4, and the rear part 5 is locked in the vehicle body by a locking means. The inner panel 2 is configure to have different plate thickness so that each portion 3, 5, 16, 17, 18 is provided with proper rigidity. The rear side 5 in the longitudinal direction of the vehicle is adjusted to have plate thickness larger than that of intermediate parts 16, 17, 18 so that the gravity center 14 of the door is placed on the side of the rear side more than the center 15 in the longitudinal direction of the vehicle.
