Abstract: There is provided an exhaust gas purification device that shows a high HC removal performance under a condition in which a rich air-fuel mixture is introduced. The exhaust gas purification device includes a substrate, a first catalyst layer, and a second catalyst layer. The substrate includes an upstream end and a downstream end. The first catalyst layer is disposed on a surface of the partition wall in an upstream region including the upstream end of the substrate. The second catalyst layer is disposed inside the partition wall in a downstream region including the downstream end of the substrate. The first catalyst layer contains a first metal catalyst and alumina-zirconia composite oxide. The second catalyst layer contains a second metal catalyst.

Abstract: A foam molded article mold includes a lower mold with a cavity space; an upper mold formed with an upper mold face portion facing a lower mold face portion of the cavity space when the upper mold has been brought together with the lower mold; a partitioning wall that projects out from the upper mold face portion, and that configures a first parting line between the partitioning wall and the lower mold face portion in a state in which the upper mold has been brought together with the lower mold; and a partition that projects out from the lower mold face portion, and that, in a state in which the upper mold has been brought together with the lower mold, partitions the cavity space together with the partitioning wall to form plural cavities, and that configures a second parting line between the partition and the partitioning wall.
