Abstract
An exhaust gas purification device includes a substrate including an upstream end and a downstream end, the substrate having a length Ls between the upstream end and the downstream end; a first catalyst layer containing first catalyst particles, extending across a first region, and being in contact with the substrate, the first region extending between the upstream end and a first position, the first position being at a first distance La from the upstream end toward the downstream end; and a second catalyst layer containing second catalyst particles, extending across a second region, and being in contact with the substrate, the second region extending between the downstream end and a second position, the second position being at a second distance Lb from the downstream end toward the upstream end. The first catalyst layer has an inner surface defining macropores.
