PROBLEM TO BE SOLVED: To provide a method for producing glass ceramic where the glass ceramic whose surface is excellent in durability has one or more titanium oxide crystals selected from the group consisting of an anatase type, a rutile type and a brookite type on the surface and to provide a photocatalytic functional formed body and a hydrophilic formed body containing the glass ceramic produced by the method. SOLUTION: The glass ceramic includes, in mol%, 15.0% or more and 88.9% or less TiO<SB>2</SB>ingredient, 11.0% or more and 84.9% or less P<SB>2</SB>O<SB>5</SB>ingredient and 0.1% or more and 50.0% or less one or more ingredients selected from the group consisting of B<SB>2</SB>O<SB>3</SB>ingredient, Al<SB>2</SB>O<SB>3</SB>ingredient, Ga<SB>2</SB>O<SB>3</SB>ingredient and In<SB>2</SB>O<SB>3</SB>ingredient to the total amount of the glass ceramic having a composition in terms of an oxide.
