<p>PROBLEM TO BE SOLVED: To provide a ceramic filter aggregate hardly causing the leakage of fluid at an outer peripheral surface. SOLUTION: The ceramic filter aggregate 9 constitutes a part of waste gas purifying device 1. In the ceramic filter aggregate 9, respective filters F1 are integrated by bonding outer peripheral surfaces themselves of plural filters F1 consisting of porous ceramic sintered body through a ceramic sealing material layer 15. The section of the aggregate 9 is subjected to external size cutting in an almost circular shape as a whole. An unevenness eliminating layer 16 consisting of ceramic material is formed at the outer peripheral surface 9c exposed by the external size cutting.</p> |
