An exhaust-gas treatment device includes a honeycomb body wound and/or stacked with at least partially structured sheet-metal layers forming channels through which an exhaust gas can flow in axial direction from an inlet side to an outlet side. A first section of the sheet-metal layers ends flush at a first end surface associated with at least one of the sides and a second section of the sheet-metal layers ends at a second end surface associated with at least one of the sides. A spacing is provided between the first and second end surfaces because a first axial length of the first section is greater than a second axial length of the second section. The spacing forms a receptacle receiving a heating body, producing a simple electrically heatable exhaust-gas treatment device into which a heating body can be integrated during or after production of the honeycomb body.
