HONEYCOMB FILTER

To provide a honeycomb filter capable of improving exhaust gas purification performance while suppressing an increase in pressure loss.SOLUTION: A honeycomb filter 100 includes: a columnar honeycomb structure 4 having porous partition walls 1 arranged so as to surround a plurality of cells 2 serving as fluid flow paths extending from a first end face 11 to a second end face 12; a plugging portion 5 is disposed at an opening on the first end face 11 side or the second end face 12 side of each cell 2; and a catalyst 14 for purifying exhaust gas is supported on the partition walls 1 of the honeycomb structure 4. The partition walls 1 have, in a state where the catalyst 14 is not supported thereon, a pore volume of pores having a pore diameter of 10 μm or less of 0.07 to 0.30 cc/g, an average pore diameter of 11 to 23 μm, and a porosity of 56 to 65%.SELECTED DRAWING: Figure 1 【課題】圧力損失の上昇を抑えつつ、排ガス浄化性能を向上させることが可能なハニカムフィルタを提供する。【解決手段】第一端面１１から第二端面１２まで延びる流体の流路となる複数のセル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体４と、それぞれのセル２の第一端面１１側又は第二端面１２側の開口部に配設された目封止部５と、ハニカム構造体４の隔壁１に担持された排ガス浄化用の触媒１４と、を備え、隔壁１は、触媒１４が担持されていない状態において、細孔径が１０μｍ以下の細孔の細孔容積が０．０７～０．３０ｃｃ／ｇであり、平均細孔径が１１～２３μｍであり、且つ、気孔率が５６～６５％である。【選択図】図１
