PROBLEM TO BE SOLVED: To provide a three-dimensional fan that is constituted of a card-board and a styrofoam core material formed in one of a rectangular shape, a cylindrical body shape and a polygonal body shape, and has low cost, light weight and safety, while having sufficient strength to be fanned, and also is recyclable as resources.SOLUTION: A three-dimensional fan comprises one piece of card-board and a core material. The one piece of card-board comprises two three-dimensional fan components of a first three-dimensional fan component integrally formed of a handle and a fan plate, and a second three-dimensional fan component substantially symmetrically formed with the above component via a center broken line, in which a ridge-fold line is provided in the middle of both three-dimensional fan components intersecting in the center broken line, the two three-dimensional fan components are folded in the central broken line to be overlaid on each other, and the handle components are fixed with each other so that the handle becomes a rectangular tube shape. The core material is inserted along between a mountain shape of the first three-dimensional fan component and a mountain shape of the second three-dimensional fan component facing the above mountain shape from the bottom of the formed handle to the center broken line. |
