To provide durable ceramics structure that a piled particulate in a reclaiming process is burned and removed perfectly because of its high thermal conductivity of an adhesive layer binding several ceramics components and no crack by vibration and pressure of an exhaust gas occurs in the adhesive layer because of its high adhesive strength.

The ceramics block is composed by binding several square rod-shaped components of the porous ceramics where longitudinally continuous pores separated with partition are arranged to the adhesive layers. The partitions work as a particle-collecting filter and the adhesive layers contain at least an inorganic binder, an organic binder and a silicon carbide fiber.
