A buoyant aerial vehicle includes a buoyant vehicle body in which gas having a specific gravity smaller than air is hermetically filled, a vertical propulsion propeller which provides vertical propulsive force, and a horizontal propulsion propeller which provides horizontal propulsive force The buoyant vehicle body is configured with flotation chambers and connecting portions. The flotation chambers are arranged at positions point-symmetric with respect to a center of the buoyant vehicle body. Central portions of the flotation chambers are bulged in a side view and the connecting portions connect the flotation chambers. The connecting portions are formed in a flat shape thinner than the central portions of the flotation chambers such that wind passages along which the air flows are formed on the connecting portions, and the wind passages are oriented in at least two directions in the plan view.
