摘要： The exhaust gas purification device according to the present invention is provided with a particulate filter disposed in an exhaust passage of an internal combustion engine and capturing particulate matter in exhaust gas discharged from the internal combustion engine. The particulate filter is provided with 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 is also provided with 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.
