ABSTRACT:
A multi-layer wiring board where a plurality of wiring boards are laminated. The wiring board comprises a flexible insulating layer having a through hole and a wiring pattern formed on the flexible insulating layer. The wiring pattern is composed at least of two conductive layers. The first conductive layer formed on the insulating layer is made of a non-metallic conductor and the first wiring pattern is formed by a laser beam. The second conductive layer is an electroplated layer formed on the first wiring pattern. The first and second conductive layers have different reflectance for a beam. The wiring board is manufactured by integrally laminating a plastic conductive supporting plate wound in a roll shape and an insulating film similarly wound in a roll shape; forming a through hole in a predetermined position of the insulating film; forming the first conductive layer on the laminated body provided with the through hole; forming the first wiring pattern by a laser beam; and forming the electroplated layer on the first wiring pattern.
