The catalytic converter has a casing with two one-piece shells. These each have a curved section and flanges projecting outward away therefrom. The flanges are welded to one another in pairs and make an angle with one another at least in a substantial part of their lengths and, for example, over their entire lengths. In the production of the catalytic converter, the shells can be produced simply and economically with the aid of a shaping process. After at least one dimensionally stable core and an elastically deformable intermediate layer surrounding this core have been arranged between the two shells, the latter are pressed against one another with a predetermined compressive force and are welded to one another. In the mass production of catalytic converter, their cores can be installed readily and without damage in the casing, even in the case of relatively large deviations from the intended ideal shapes and ideal dimensions.
