[Problems to be solved by the device]

 However, in the conventional mosaic pieces as described above, the solids that can be formed are limited to polygons, and it is difficult to form solids that include curved surfaces, and there are many polygons that cannot be formed. The design when used as a container was severely restricted.

In addition, in the conventional mosaic piece, the joint portion between the adjacent mosaic pieces is provided with appropriate play to absorb the error in the meshing portion, and the protrusion piece and the female engaging portion can be easily formed. The width (W1) of the base end portion (2c) of the projecting piece (2) on each side (1a) of the base piece (1) is set so that two adjacent projections can be engaged with each other. Since the gap (W2) between the pieces (2) is smaller (Wl <W2), there is a gap in at least one of both ends of the projecting piece (2) and the female engaging portion (3) that engage with each other. The part (S) is always formed, which has a problem that the appearance is significantly impaired.

Further, in the conventional case, when the base piece (1) is bent to form a two-dimensional surface, the projection piece (2) and the projection piece (2) at the corner of the base piece (1) are attached to the forehead. There is also a problem that) interferes with the bending of the base piece (1).

In view of the above problems of the prior art, the present invention can form a wide variety of solids including curved solids, and does not create a space in the connecting portion.
