Electrically heatable honeycomb body assembly having an electrical connection of a plurality of sheet metal layers

A honeycomb body assembly, comprising:

• a honeycomb body having a metal casing with an inner periphery, a radial direction, an axial direction and a bushing passing through said metal casing;
• alternately disposed coarsely structured sheet metal layers and finely structured or smooth sheet metal layers together forming a stack with an uppermost sheet metal layer, a lowermost sheet metal layer, an inlet side, an outlet side, a connection region and channels between said sheet metal layers through which a gas can flow from said inlet side to said outlet side in said axial direction;
• a connection pin running perpendicular to said sheet metal layers in said radial direction and passing through said inner periphery in said bushing in an electrically insulating manner;
• and
• at least one electrically conductive intermediate piece surrounding a plurality of said sheet metal layers in said connection region and providing a metallic electrical connection of said connection pin to at least two of said sheet metal layers.
