PROBLEM TO BE SOLVED: To provide a hollow structure of a specified shape by suppressing the eccentricity of a photocuring resin by gravity. SOLUTION: This photocuring hollow structure comprises an inner bag layer 2 allowing fluid to be pressingly filled therein, a base material layer 3 overlapped with the outer periphery of the inner bag layer 2 and impregnated with the photocuring resin, and a light transmitting covering layer 4 overlapped with the outer periphery of the base material layer 3. When not used, the structure is stored in a flexible and generally light transmitting storage bag or storage case. When used, the structure is taken out from the storage bag or case, and the fluid is pressingly filled into the inner bag layer to inflate the entire part of the bag or case to cure the base material layer 3 by direct sunshine or artificial light source beam transmitting through the covering layer 4 so as to form a hollow structural molded product of a specified shape. The base material layer 3 comprises a composite member 9 as a reinforced fiber layer impregnated with the photo-curing resin and a lattice-shaped net 10 overlapped with the composite member 9 to prevent the photocuring resin from flowing.
