Abstract: Shaped articles 42, 43 are inseparably and integrally formed of a colorless transparent material or a colored transparent material, and a peripheral surface has an uneven shape. In the shaped article 42 formed by a flat and irregular polyhedron and the article 43 formed by a plurality of recesses 44 shaped by burning, the entered light is refracted and reflected in various directions and radiated outside the shaped articles to be seen by a viewer. In the shaped article 43, a housed object 45 is visually complemented by the shadowed part of the recesses 44. Thus, the light is seen by the viewer. The visual effect of making the front surface shine brightly can be kept by dispersing and reflecting incident light. In addition, a risk of bodily injury and environmental disaster caused by light concentration can be avoided by suppressing transmission light irradiated from the irregular polyhedron and the recesses 44.
