An amorphous inorganic ceramic material including silicon, carbon and oxygen is provided. In the ceramic material, the average elemental ratio between silicon, carbon and oxygen is represented by a compositional formula: SiC.sub.aO.sub.b wherein, a is a number that satisfies: 0.5.ltoreq.a.ltoreq.3.0, and b is a number that satisfies 0.5.ltoreq.b.ltoreq.4.0), the material has a siloxane skeleton formed of Si--O--Si bonds, and the hydrogen mass fraction is within a range from 0 to 1% by mass. The material exhibits excellent heat resistance, wettability with other materials, strength and elastic modulus, and is useful as a reinforcing material for composite materials, or as an exhaust gas filter material or the like.
