ABSTRACT:
An electrically heatable honeycomb body includes an axis, an inner region surrounding the axis, and an outer region spaced apart from the axis. At least one stack has at least one sheet metal layer and is disposed between the inner region and the outer region. The stack is wound in the form of a spiral with a multiplicity of windings around the inner region. The windings include a plurality of windings being adjacent one another and spaced apart from one another and electrically insulated, in pairs. A multiplicity of bridges each mechanically and electrically connect together a respective two of the adjacent and spaced-apart windings. The windings and the bridges form a multiply branched current path for an electrical current flowing between the inner region and the outer region. Each of the windings is completely part of the current path.
