To provide a ceramic filter assembly having excellent strength and reproduction efficiency.

The ceramic filter assembly 9 has filter core members 21 and low-thermal conductivity members 22. The members 21 are formed by bonding the outer peripheral surfaces of a plurality of prismatic honeycomb filters F1 to each other across ceramic sealing material layers. The prismatic honeycomb filters F1 consist of porous ceramic bodies of a non-oxide system essentially consisting of silicon carbide. The members 22 consist of ceramic materials having the lower thermal conductivity than the thermal conductivity of the porous ceramic bodies forming the members 21. The members 22 are bonded across the ceramic sealing material layers on the outer peripheral surfaces of the members 21 in the state of being arranged on the outer sides of the members 21.
