1. A heating conductor for an exhaust gas heating arrangement for an exhaust gas system for an internal combustion engine, the heating conductor being configured to be plate-like and being cut out from a metal flat material and comprising:
a plurality of heating conductor sections extending in a heating conductor section longitudinal direction (H), wherein at least one of:
a first portion of said plurality of heating conductor sections are arranged to form a configuration of the heating conductor wound in a meandering manner at least in regions thereof, and,
a second portion of said plurality of heating conductor sections form a configuration of the heating conductor wound spirally at least in regions thereof;
at least one throughflow opening provided in at least one of said plurality of heating conductor sections for passing exhaust gas therethrough, said at least one throughflow opening being elongated in a through flow opening longitudinal direction (D) corresponding to said heating conductor section longitudinal direction (H) and having a longitudinal end region; and,
a flow-conducting element in association with said at least one throughflow opening, said flow-conducting element being configured to extend, starting from said longitudinal end region, in said through flow opening longitudinal direction (D) at least partially along said throughflow opening.
