Claims

[Scope of utility model registration request]

A catalyst carrier formed by stacking a flat plate and a corrugated plate on top of each other and winding them in a roll shape and providing a plurality of cell passages defined by the corrugations of the corrugated plates in a honeycomb shape is disposed inside a cylindrical cover, and the cells are arranged in a cylindrical cover. A catalytic converter that allows exhaust gas to pass through a passage, characterized in that a cutout portion where adjacent cell passages communicate with each other midway is provided by cutting out a part of the flat plate or the corrugated plate. converter.
