Abstract
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.
