A catalytic converter has a carrier with a cell structure, and a precious metal catalyst carried on the carrier. The carrier includes a first carrier and a second carrier. The second carrier is provided downstream of the first carrier in a gas flow direction of gas that flows into the catalytic converter. The first carrier has a first peripheral region and a first center region that has a lower cell density than the first peripheral region. The second carrier has a second center region and a second peripheral region that has a lower cell density than the second center region.
