Claims

[Scope of utility model registration request]

A corrugated metal plate and a flat plate are stacked, and these are wound multiple times to form a core part, and this core part is housed in a cylindrical container.
A corrugated plate and a flat plate located on the outer periphery of the core in a metal catalytic converter in which an annular member fixed to the cylindrical container is brought into contact with the cylindrical container to restrict axial movement of the core within the cylindrical container. A metal catalytic converter characterized in that through-holes are formed in the corrugated plates and the flat plate, excluding at least the flat plate located at the outermost periphery.
