Abstract

There is disclosed an exhaust gas purifying device in which an exhaust gas emitted from a direct injection type gasoline engine evenly flows into an end face of a plugged honeycomb structure and which is capable of efficiently removing a particulate matter. An exhaust gas purifying device 1 includes a honeycomb catalyst body 10, a plugged honeycomb structure 20 and a can member 30 to receive therein the honeycomb catalyst body 10 and the plugged honeycomb structure 20, and the plugged honeycomb structure 20 disposed at a position on a downstream side of the honeycomb catalyst body 10 is designed so that a pressure loss in an end face central region of at least one of a second inflow side end face 21 and a second outflow side end face 22 of a second honeycomb substrate 25 is larger than a pressure loss of an end face circumferential region positioned around the end face central region.
