Claim 0:
1. An exhaust gas heater for an exhaust gas system of an internal combustion engine, the exhaust gas heater defining an exhaust gas longitudinal axis (L) and comprising:
a carrier arrangement and a heat conductor arrangement carried on said carrier arrangement;
said heat conductor arrangement having at least one heat conductor for conducting a current flow therethrough;
said carrier arrangement comprising two carrier elements receiving said heat conductor arrangement therebetween in the direction of said exhaust gas heater longitudinal axis (L);
a plurality of carrier arrangement support units carrying said at least one heat conductor in an electrically insulating manner with respect to each of said carrier elements;
at least one of said carrier arrangement support units including a first carrier arrangement support element having a curved first support face and a second carrier arrangement support element having a curved second support face;
wherein,
in said at least one of said carrier arrangement support units, said first carrier arrangement support element has a substantially non-curved heat conductor support face supported at one heat conductor of said at least one heat conductor of said heat conductor arrangement and, at a side facing away from said at least one heat conductor of said at least one heat conductor of said heat conductor arrangement, has said curved first support face
and said second carrier arrangement support element has a substantially non-curved carrier arrangement support face supported at said carrier arrangement and, at a side facing away from said carrier arrangement, has said curved second support face supported at said curved first support face of said first carrier arrangement support element.
