<P>PROBLEM TO BE SOLVED: To provide a glass ceramic which is easily handled in the manufacturing process, hardly causes surface peeling and the degradation with time and has high photocatalytic characteristics, a method of manufacturing the same and particularly to provide a glass ceramic formed into a desired shape by a relatively simple method and having high photocatalytic activity. Ž<P>SOLUTION: The glass ceramic comprises a crystalline composition containing at least one kind selected from TiO<SB>2</SB>or its solid solution and a vitreous composition containing at least one kind selected from an SiO<SB>2</SB>component, a B<SB>2</SB>O<SB>3</SB>component or a P<SB>2</SB>O<SB>5</SB>component, wherein the vitreous composition is a matrix component. The crystalline composition can have a crystal type having high photocatalytic performance. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
