Abstract
An exhaust gas purification device capable of reducing a pressure loss and capable of improving an exhaust gas purification performance includes a honeycomb substrate and an outflow side catalyst. The honeycomb substrate includes a porous partition wall defining a multiple cells extending from an inflow side end surface to an outflow side end surface. The outflow side catalyst is in an inner region on the outflow cell side of the partition wall in an outflow side catalyst-disposed range extending from an outflow side end of the partition wall to a position apart toward an inflow side along an extending direction.
