Abstract
A flexible circuit board and a method for production thereof in which in cases where elastic wiring in movable parts is required, the wiring can be made to expand and contract with a simple arrangement, and the circuit board is excellent in weight and size reduction, and breaking or disconnection and exfoliation of a wiring layer do not take place easily, even in cases where the circuit board is deformed in a repeated manner. The flexible circuit board which has an insulating film made of a thermoplastic resin, a wiring layer formed on the insulating film, and an insulating layer made of a thermoplastic resin and formed on the wiring layer. A spiral part shaped into a spiral shape is provided in at least a part of the flexible circuit board, and the flexible circuit board is constructed to be expandable and contractable, and/or torsionally deformable in the spiral part.
