Original Abstract Submitted

A printed circuit board includes: an insulating base film; and a plurality of wiring portions foamed on a surface of the base film. The wiring portions include a seed layer directly or indirectly layered on the surface of the base film and a metal layer layered on the seed layer. The base film has a wiring area including the plurality of wiring portions and a non-wiring area not including the wiring portions. The plurality of wiring portions include at least one outermost boundary wiring portion and a plurality of inner wiring portions. The outermost boundary wiring portion is formed on an outermost-side of the base film in the wiring area and at a boundary between the wiring area and the non-wiring area. An average thickness of the outermost boundary wiring portion is 40μm or more. An average width of the outermost boundary wiring portion is 30 μm or more.
