摘要： PROBLEM TO BE SOLVED: To provide a tile to provide a sufficient decoration function and be excellent in decoration properties and durability. SOLUTION: A plurality of light tranmissive substances 2 continued from a surface 1a of a tile body 1 to a back 1b thereof are arranged in a good order state in a thin plate-form tile body 1 approximately in a square shape. The tile body 1 is molded by using concrete or mortar mixed with pigment and alkali resistance fibers and neutralized through reaction with acid. The light transmissive substance 2 consists of glass pieces, and a light transmissive material piece, such as alkali pieces, and has an alkali resistance film 4 formed such that uneven surface paint 5 is applied on an outer surface. Light is transmitted from the surface 1a to the back 1b of the tile body 1. Adhesion of the light transmissive substance 2 to the tile body 1 is high and besides, the light transmissive substance 2 is not influenced by the alkali component of the tile body 1.
