Abstract
A honeycomb filter includes a plurality of cells and porous cell walls. The plurality of cells defines exhaust gas passages. The plurality of cells includes exhaust gas introduction cells and exhaust gas emission cells. Each of the exhaust gas emission cells is adjacently surrounded fully by the exhaust gas introduction cells across the porous cell walls. The exhaust gas introduction cells include first exhaust gas introduction cells and second exhaust gas introduction cells. A cross-sectional area of each of the exhaust gas emission cells in a cross section perpendicular to a longitudinal direction of the plurality of cells is equal to or larger than a cross-sectional area of each of the second exhaust gas introduction cells in the cross section. The exhaust gas introduction cells and the exhaust gas emission cells have one of a first structure and a second structure in the cross section.
