PROBLEM TO BE SOLVED: To provide a soft type airship capable of restraining sloshing by strengthening a connecting part of a secret wall and a skin and simplifying lay constitution of a film material, having durability in an extensive temperature range and capable of stably floating itself up to a high altitude. SOLUTION: It is devised to positively give tensile force to a diaphragm by partitioning the inside of a hull into a large number of rooms 42 including helium bladders 27 by the diaphragm 24, connecting the diaphragm 24 to the hull skin 22 in a forked shape by using a diaphragm core 25, forming a bulkhead connecting space part 45 on the connecting part of the skin and the diaphragm core and adding internal external differential pressure to the bulkhead connecting space part 45 by equalizing pressure of the space part to outside air by providing a blow hole 23 on the skin. The helium bladders 27 stored in each of the rooms are connected to a helium vent pipe 26 provided out of the airship, and a longitudinal position of a center of gravity can be moved by transferring helium between the helium bladders.
