PROBLEM TO BE SOLVED: To provide an airship that allows filling of a large amount of air, is appropriate to high altitude flight, is relatively light, and has high controllability. SOLUTION: The airship 1 comprises a hull 10 constituted by a flexible housing, and a plurality of air bags (a bow side ballonet 60, a stern side ballonet 70 and a center ballonet 80) arranged in the longitudinal direction in this hull 10. Floating gas is filled into a space other than the air bags in the hull 10. A plurality of rope bodies 20-50 are extended vertically in the hull 10, the right and left upper ends of each air bag are restricted vertically movably along the rope bodies 20-50, and the upper end of each air bag moves upward by filling of the air and moves downward by exhaustion of the air.
