Zusammenfassung:	A glass ceramic sintered body having a small dielectric loss in a high frequency band of 10 GHz or higher and a wiring substrate using the same are provided. The glass ceramic sintered body contains crystallized glass, an alumina filler, and silica. The content of the crystallized glass is 45 mass % to 85 mass %, the content of the alumina filler is 14.8 mass % to 50.1 mass % in terms of Al2O3, and the content of silica is 0.2 mass % to 4.9 mass % in terms of SiO2.
