Zusammenfassung:The utility model provides a honeycomb filter which is excellent in trapping performance and low in pressure loss. The honeycomb filter is provided with: a columnar honeycomb structure section (4) having porous partition walls (1) disposed so as to surround a plurality of cells (2) extending from a first end surface (11) to a second end surface (12); and a sealing part (5) which is disposed at any opening of each cell (2), and which satisfies all of the following formulae (1)-(6), where D10, D50, and D90 are the pore diameters ([mu] m) at which the cumulative pore volume reaches 10%, 50%, and 90% of the total pore volume, respectively, in the pore diameter distribution of the partition wall (1) as determined by structural analysis. (1) 17.5 [mu] m < D50 < 24.0 [mu] m (2) D90 < 55.2 [mu] m (3) (logD90-logD10)/logD50 < 0.60 (4) logD90/logD50 < 1.30 (5) logD50/logD10 < 1.38 (6). 本实用新型提供一种捕集性能优异且压力损失降低的蜂窝过滤器。该蜂窝过滤器具备:柱状的蜂窝结构部(4),其具有多孔质的隔壁(1),该隔壁(1)配置成包围从第一端面(11)延伸至第二端面(12)的多个隔室(2);以及封孔部(5),其配设于各隔室(2)的任一开口部,在通过结构解
