摘要： A particulate filter provided in the exhaust gas purification device according to the present invention includes: a wall-flow part 20 having an inlet-side cell 22 that is open only at an end on an exhaust gas inflow side, an outlet-side cell 24 that is adjacent to this inlet-side cell 22 and is open only at an end on an exhaust gas outflow side, and a porous wall 26 that partitions the inlet-side cell 22 from the outlet-side cell 24; and a straight-flow part 30 having a through cell 32 that penetrates the filter in an axial direction thereof and is open at the end on the exhaust gas inflow side as well as the end on the exhaust gas outflow side. Here, in a cross section of the filter 100 orthogonal to its axial direction, cross-sectional areas of the inlet-side cell 22 and the outlet-side cell 24 present in an outer peripheral region of the cross section are larger than cross-sectional areas of the inlet-side cells 22 and the outlet-side cell 24 present in a central region of the cross section.
