发明名称 Honeycomb ceramics filter.
摘要 There is disclosed a honeycomb ceramics filter, wherein an average pore diameter X ( mu m) and partition wall thickness W ( mu m) of the filter satisfy a relation of 10 ≥ W/X. According to this filter, while a predetermined trapping efficiency is maintained, a pressure loss can be prevented from increasing to be not less than a predetermined pressure loss even with use for a long period.
