Disclosed is a novel lithium ion conductive glass ceramic that is relatively stable with respect to metallic lithium and has improved ion conductivity, and a method for producing the same. Li + : 7 to 15%, X2 + : more than 0 to 4% (where X2 + is at least selected from the group consisting of Ca2 + , Ba2 + , Sr2 + , and Ra2 +) 1), Mg 2+ : 20 to 50%, Al 3+ : 5 to 20%, and Si 4+ : 30 to 60%, and in terms of anion%, F − : 5 to 35%, And O 2− : 35 to 95%, a lithium ion conductive glass ceramic.
