Patent ID: 8071885

Claim:
A printed circuit board that can be used being folded, comprising: a base insulating layer that includes first and second regions being adjacent to each other and can be folded along a boundary between said first region and said second region; a plurality of conductor patterns provided on said base insulating layer over said first and second regions so as to be substantially along a virtual axis line that is perpendicular to said boundary; and a cover insulating layer provided on said base insulating layer so as to cover said plurality of conductor patterns, wherein each of said plurality of conductor patterns includes a first portion positioned in said first region and a second portion positioned in said second region, and at least one of said first portion and said second portion has a nonlinear shape such that at least part of said first portion does not overlap with at least part of said second portion when said base insulating layer is folded along said boundary, and said first portion of a first conductor pattern of said plurality of conductor patterns and said second portion of a second conductor pattern of said plurality of conductor patterns do not overlap with each other, and said second portion of said first conductor pattern and said first portion of said second conductor pattern do not overlap with each other.
