A ceramic-steel joined body includes a ceramic body of silicon nitride, zirconia, silicon carbide, boron nitride, and alumina. The joined body also includes a steel body which has its surface carburized so that the hardness of the surface is greater than the hardness of the inside of the steel body. The ceramic body and the steel body are thermally joined using a brazing material of Ag-Cu-Ti, Ag-Cu-In-Ti, Ag-Ti, Cu-Ti, Ag-Cu-Ni-Ti, Ag-Cu or Ag-Cu-In.
