Abstract
An electrically heatable catalytic converter (100, 200, 300, 400) for treating a gas stream, especially of the exhaust gas stream of an internal combustion engine, the electrically heatable catalytic converter (100, 200, 300, 400) has a tubular housing (101, 201, 301, 401), an interior space enclosed by the tubular housing (101, 201, 301, 401), and a porous structure, which is arranged in the interior space of the tubular housing (101, 201, 301, 401) and can be heated by an electric heater, in which the electric heater is a mineral-insulated heater (103, 203, 303, 403) with a heat conductor (104, 204, 304, 404), with at least one front-side connection opening (109, 209, 210, 309, 409) and with at least one outer metal jacket (108, 208, 308, 408), the mineral-insulated heater (103, 203, 303, 403) has at least one section (103, 203a, 203b, 303a), which is passed through a housing wall.
