1. An exhaust-gas treatment device, comprising: a honeycomb body through which an exhaust gas can flow; said honeycomb body having an inlet side, an outlet side, an axial direction and at least partially structured, wound or stacked sheet-metal layers forming channels configured to conduct an exhaust gas flow in said axial direction from said inlet side to said outlet side, said sheet-metal layers include alternately disposed smooth sheet-metal layers and corrugated sheet-metal layers; said honeycomb body having a first end surface associated at least with said inlet side or said outlet side and a second end surface associated at least with said inlet side or said outlet side, said second end surface being at least partially defined by at least one terminal end surface of one of said corrugated sheets; said sheet-metal layers including a first section of sheet-metal layers ending flush at said first end surface and a second section of sheet-metal layers ending at said second end surface; said first section of sheet-metal layers having a first length in said axial direction, said second section of sheet-metal layers having a second length in said axial direction, said first length being greater than said second length defining a spacing between said first and second end surfaces; said spacing forming a receptacle; and a heating element disposed in said receptacle.
