Abstract
A flexible circuit board includes a substrate and a circuit unit formed on the substrate. The substrate has two carrying segments and a connecting segment, and the two carrying segments are connected by the connecting segment. The circuit unit has a plurality of conductive lines and at least one connecting line, and each conductive line and the connecting line are separated from each other. The conductive lines are respectively formed on the two carrying segments, and the connecting line is formed on the connecting segment and the two carrying segments. Two opposite ends of each carrying segment are configured to connect with each other to form a tubular structure, and two opposite ends of the connecting line are configured to connect to two adjacent conductive lines respectively formed on the two tubular structures, thereby the circuit unit is formed as a coil.
