A metal carrier for a catalytic converter

摘要

A first honeycomb structure (11) not bonded with brazing filler metal and having a catalyst-carrying layer, and two second honeycomb structures (12) bonded together with brazing filler metal and without applying a catalyst-carrying layer arranged before and after the first honeycomb structure (11) are aligned coaxially inside a cylindrical casing (3). The first honeycomb structure (11) preferably has a greater concentration of air passages than the second honeycomb structures (12) and moreover, is spaced a fixed distance from each of the second honeycomb structures.
