An electrically heatable catalytic converter for internal combustion engines is provided. This catalytic converter includes a honeycomb multi-layered core member wound around an electrode. The multi-layered core member consists of a plurality of flat metal foil sheets and a plurality of corrugated metal foil sheets arranged alternately and bonded to each other for preventing the core member from telescoping in the direction of exhaust gas flow, especially, during high-load engine operation.
