(57) [Problem] To provide a product having good productivity, low cost, and high connection reliability. SOLUTION: In the flexible multilayer wiring board of the present invention, the first conductive pattern 5 provided on the first flexible insulating substrate 2 and the second conductive pattern provided on the second flexible insulating substrate 12 are the first conductive pattern. Since the first conductive material 23 filled in the through-holes 2a is used to conduct, the flexible multi-layer wiring has good productivity, is inexpensive, and has high connection reliability as compared with the conventional gold-plated one. A substrate can be provided. |
