A ceramic composition being fired at a low temperature and having a high strength, which comprises, in its structure, SrAl2Si2O8 crystals and Al2O3 crystals, wherein the SrAl2Si2O8 crystals consist of hexagonal crystals alone or of hexagonal SrAl2Si2O8 crystals and monoclinic SrAl2Si2O8 crystals, and exhibits a peak intensity ratio represented by I101/(I101 + I002) X 100 of 5 % or more, where I101 represents a peak intensity for (101) face of a hexagonal SrAl2Si2O8 crystal and I002 represents a peak intensity for (002) face of a hexagonal SrAl2Si2O8 crystal. |
