发明名称 HONEYCOMB FILTER
摘要 There is provided a honeycomb filter obtained by bonding, into one piece, a plurality of honeycomb segments comprising partition walls having filtering function, and a number of through-holes divided from each other by the partition walls and extending in an axial direction. Predetermined through-holes are plugged at one end face of the filter, and the remaining through-holes are plugged at the other end face of the filter. The honeycomb filter is characterized in that the honeycomb segment disposed in a peripheral portion of the honeycomb filter has a lower average bulk density than that of the honeycomb segment disposed in a central portion. <IMAGE>
