Abstract

An exhaust gas heater for an exhaust gas system of a combustion engine includes a carrier and a heating conductor supported on the carrier. The heating conductor includes a heating region arranged on an axial side of the carrier, wherein the heating conductor is electrically uninsulated in its heating region at least in part. A holding arrangement has at least one holding unit which holds the heating conductor on the carrier in its heating region. The holding unit includes at least one electrically conducting holding block which is in contact with the heating conductor in an electrically uninsulated region of the heating region. The holding block is electrically insulated with respect to the carrier.
