ABSTRACT:
The electrically heated catalytic converter of the present invention has a substrate, for a catalyst, which is formed as a laminated assembly of corrugated metal sheets and plain metal sheets. The corrugated metal sheet has an insulating coating made of an alumina Al.sub.2 O.sub.3, and the plain metal sheet has no insulating coating. Local conductive connections are formed between the layers of the metal sheets by soldering the metal sheets using strips of zirconium solder foils interposed between the layers of the metal sheets. The strips of solder foils are arranged in such a manner that the strips of solder foil disposed on both sides of the corrugated metal sheet defines a single electric path in the corrugated metal sheet which connects the solder foils on both sides of the corrugated metal sheet. Since the solder foils on both sides of the corrugated metal sheet are connected by only one electric path, the electric resistance between the solder foils is maintained at a relatively high value and the local conductive connections can be heated by a relatively small electric current.
