PROBLEM TO BE SOLVED: To provide a decorative structure capable of being easily assembled and disassembled and having a highly decorative appearance based on curved lines and curved surfaces. SOLUTION: The decorative structure is a hexahedral one made of a sheet material. The top face and the bottom face have the same rectangular shape (including the square shape) and a pair of opposing side faces each have a convex surface, and another pair of opposing side faces in the other set each has a concave surface. These convex and concave surfaces may be either the curved surface or surfaces formed by connecting planes in a dog-legged pattern. The top face and the bottom face are provided with engaging means consisting of a projected piece on one side and a slit on the other into which the piece is fitted. Thereby a plurality of the decorative structures can be connected together. In the case when the top face and the bottom face have the rectangle shape and does not have the square shape, two types of structure, i.e., a type of structure having a rectangle consisting of long sides of the convex long surface and short sides of the concave surface and a type of structure having a rectangle consisting of long sides of the concave surface and short sides of the convex surface. By combining them as a set, a combination of the decorative structures rich in variation can be constituted. COPYRIGHT: (C)2006,JPO&NCIPI
