Electrically heatable honeycomb body of a catalytic converter equipped in an exhaust system of an internal combustion engine

An electric heater comprising

• a first electrode and a second electrode;
• a multi-layered honeycomb body disposed between said first and said second electrodes, said multi-layered honeycomb body comprising a plurality of conductive foil layers, each conductive foil layer being electrically insulated from adjacent conductive foil layers in a direction across said conductive foil layers;
• a plurality of bonding parts comprising a first, a second, a third and a fourth bonding part, wherein said first bonding part and said second bonding part are disposed on a first bonding line extending across said plurality of conductive foil layers and said third bonding part and said fourth bonding part are disposed on a second bonding line also extending across said plurality of conductive foil layers, wherein bonding parts aligned on the same bonding line are disposed on every other conductive foil layer and wherein said first, said second, said third and said fourth bonding parts are not disposed on the same conductive foil layer.
