1. An implantable nerve electrode, comprising:an electrically insulating substrate with a plurality of conductive paths running therein,
and terminal contacts,
the plurality of conductive paths connecting the electrode contacts to the terminal contacts, and the electrode contacts configured to connect to nerves of a nervous system, each single one conductive path of the plurality of conductive paths having an individual, at least partial jacket from a mechanically rigid and electrically well insulating polymer which is applied in a planar manner, each conductive path with its individual, at least partial jacket being embedded in silicone which forms the electrically insulating substrate, each jacket being separated from each other jacket by silicone,
wherein the polymer comprises one of parylene, parylene C, polyethylene, and polypropylene, and
wherein the plurality of conductive paths, the electrode contacts, and the terminal contacts are made from a laser structured metal foil.
