To provide a metal catalyst carrier of a catalyst converter for internal combustion engines wherein the production is made easy and the cost is lowered by eliminating the requirement of joining metal sheets, and film-out or displacement of an outer cylinder can be prevented.

In a metal catalyst carrier of a catalyst converter for internal combustion engines that is formed by folding one strip metal sheet 13 to form accordion pleats and forming layers of the metal sheet 13, a wire 19 is woven in along folds 13a of the metal sheet 13, and exposed parts of the wire 19 are fixed to an outer cylinder for housing the metal catalyst carrier or to the metal sheet 13 constituting the metal catalyst carrier.
