A flexible wired circuit board that is provided can improve the yield per sheet and the production efficiency of the wired circuit board and thus to reduce the production costs when a plurality of flexible wired circuit boards are formed and aligned on the sheet. The flexible wired circuit board includes a first wired circuit board portion having a first terminal portion, a second wired circuit board portion having a second terminal portion, and a connecting portion for connecting the first wired circuit board portion and the second wired circuit board portion. The first wired circuit board portion and the second wired circuit board portion are disposed adjacent to each other at one end of the connecting portion, and the first wired circuit board portion is foldable over the other end with respect to the connecting portion.
