。[Claims for Utility Model Registration] In a catalytic converter in which a catalyst carrier is provided with a large number of holes, the opening area of the holes in the central portion of the catalyst carrier is smaller than the opening area of the holes in the outer peripheral portion of the catalyst carrier. A catalytic converter characterized in that the wall thickness between the holes in the central portion of the catalyst carrier is larger than the wall thickness between the holes in the outer peripheral portion of the catalyst carrier.
