An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a heating conductor. The heating conductor is constructed from flat material which is elongate in a heating-conductor longitudinal direction and has heating-conductor broad sides situated opposite one another in a heating-conductor thickness direction and heating-conductor flat sides situated opposite one another in a heating-conductor width direction. A plurality of formations, which follow one another in the heating-conductor longitudinal direction or/and follow one another in the heating-conductor width direction, are oriented substantially in the heating-conductor thickness direction and have varying formation heights in the heating-conductor width direction.

A mixer assembly unit, for an exhaust system exhaust gas treatment unit of an internal combustion engine, mixes exhaust gas discharged by the internal combustion engine with reactant. A mixing section (), downstream in relation to a reactant release device (), mixes exhaust gas, flowing in an exhaust gas flow direction, with reactant. The mixing section includes a core flow duct (), extending in a direction of a mixing section longitudinal axis (L), through which a first exhaust gas partial stream (T) flows. A second exhaust gas partial stream (T) flows through a jacket flow duct () surrounding the core flow duct and separated from the core flow duct by an inner wall (). The reactant release device releases reactant into the core flow duct or/and into the first exhaust gas partial stream. A mixer () is provided at an upstream end area () of the mixing section.
