Abstract

An exhaust-gas treatment device for arrangement in an exhaust system of a motor vehicle, having a heating element, which is assigned to an exhaust-gas aftertreatment component, for example, a catalytic converter. The heating element is formed by a heating conductor and by a holder coupled to said heating conductor, wherein the holder extends over the cross-sectional area of the heating element, and the holder is formed by a lattice-like structure, wherein the lattice-like structure is formed by arcuate spokes which are coupled to one another in an irregular manner, wherein the heating conductor and the holder have a basin-like configuration as viewed in longitudinal section in an exhaust-gas flow direction.
