A conductor in composite is disclosed. In various embodiments, an electrically conductive structure, such as an electrically conductive metal, is sandwiched between insulating material and two or more layers of fiber reinforced composite material, to form a stack that is used to form a composite structure that includes the electrically conductive layer. The layer may comprise an electrical line, trace, bus, etc. to conduct electricity from one location to another within the composite structure, such as to connect a battery or other power source at one location to an electrical load at another location.
