In the catalytic converter, the metal catalyst carrier is formed by laminating corrugated plates and flat plates alternately in the longitudinal direction, and the introduced exhaust gas is transferred to the end face of the metal catalyst carrier on the exhaust gas inlet side. A catalytic converter characterized in that a plurality of rectifier plates are integrally provided to guide the carrier in the longitudinal direction. (2) The rectifying plate has a sandwich structure consisting of a protruding piece of corrugated plate protruding toward the exhaust gas inlet side and a protruding piece provided on a flat plate sandwiching the protruding piece. Catalytic converter according to item 1. (3) The catalytic converter according to claim 1, wherein the baffle plate is a flat protruding piece that protrudes toward the exhaust gas inlet side.
