| description | To provide a honeycomb filter that has excellent collection performance and an increase in pressure loss is suppressed.SOLUTION: The honeycomb filter comprises a columnar honeycomb structure part 4 having a porous bulkhead 1 arranged to surround a plurality of cells 2, and a seal-up part 5 arranged at an opening part of either of the cells 2. The bulkhead 1 is constituted of a material including cordierite as a main component. The number of pieces of pores with a circular-corresponding diameter of over 3.0 μm existing on a surface of the bulkhead 1 per unit areas is 1400/mm2 or more. In a pore diameter distribution in which cumulative pore volumes of the bulkhead 1 are distributed where a horizontal axis represents log pore diameters and a vertical axis represents log differential pore volumes (cm3/g), a half value range at a first peak including the maximum value of the log differential pore volumes is 0.30 or less.SELECTED DRAWING: Figure 1
【課題】捕集効率に優れ且つ圧力損失の上昇が抑制されたハニカムフィルタを提供する。【解決手段】複数のセル２を取り囲むように配置された多孔質の隔壁１を有する柱状のハニカム構造部４と、セル２のいずれか一方の開口部に配設された目封止部５と、を備え、隔壁１が、コージェライトを主成分として含む材料から構成され、隔壁１の表面に存在する円相当径３．０μｍ超の細孔の単位面積当たりの個数が、１４００個／ｍｍ２以上であり、隔壁１の累積細孔容積を、横軸をｌｏｇ細孔径とし、縦軸をｌｏｇ微分細孔容積（ｃｍ３／ｇ）として示した細孔径分布において、ｌｏｇ微分細孔容積の最大値を含む第一ピークの半値幅が、０．３０以下である。【選択図】図１ |
