Abstract
An exhaust-gas heater for an exhaust-gas system of an internal combustion engine includes a carrier arrangement and a heating-conductor arrangement, which is carried on the carrier arrangement, and which has at least one heating conductor. The carrier arrangement includes an annular first carrier element, which surrounds an exhaust-gas-heater longitudinal axis, and a plurality of second carrier elements, which are formed separately from the first carrier element and are connected to the first carrier element in a first connecting region and to a coupling region of the heating-conductor arrangement in a second connecting region.
