PROBLEM TO BE SOLVED: To provide a method for producing a 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 Nb<SB>2</SB>O<SB>5</SB>ingredient, Ta<SB>2</SB>O<SB>5</SB>ingredient, WO<SB>3</SB>ingredient and MoO<SB>3</SB>ingredient to the total amount of the glass ceramic having a composition in terms of an oxide.
