PROBLEM TO BE SOLVED: To provide a low thermal expansion ceramic joint having the bending strength and stiffness almost same to a sintered body and having a small dimensional change with time. SOLUTION: In the low thermal expansion ceramic joint formed by joining sintered compact themselves consisting of the low thermal expansion ceramic without blending an inclusion, a material constituting the sintered body is composed of lithium aluminosilicate, silicon carbide and/or silicon nitride and an average thermal expansion coefficient at 20-30°C is -1×10<SP>-6</SP>to 1×10<SP>-6</SP>/°C.
