Abstract
A catalyst carrier having a honeycomb structure made of metal sheets and used for a catalytic convertor for treating an exhaust gas of an internal combustion engine. The catalyst carrier is made of layers, each having a plain sheet, and at least one corrugated sheet applied on the plain sheet and having a width smaller than that of the plain sheet so that, laterally of the corrugated sheet, a portion of the plain sheet is not occupied by the corrugated sheet. The portion without the corrugated sheet is in face to face contact with a portion having a corrugated sheet on an adjacent layer, and as a result, a lateral engagement is obtained between the corrugated sheets of the facing layers, thereby preventing the layers from being laterally displaced along at least one direction.
