Abstract

An exhaust gas heater, for an internal combustion engine exhaust system, includes a support (22) with an outer circumferential area (24), arranged radially outside in relation to a heater longitudinal axis (A), and a central area (26). A heating conductor (42) is carried at the support and includes a helically wound heating section (44) on a first axial side (34) of the support. The central area is axially offset in a direction of the first axial side of the support in relation to the outer circumferential area such that a radially outer end section of the heating section, which outer end section is located in the area of the outer circumferential area of the support, and a radially inner end section (48) of the heating section, which inner end section is located in the area of the central area of the support, are axially offset in relation to one another.
