1. A flexible wiring board connecting a first component including a curved surface to a second component opposed to the first component and including a flat surface, the flexible wiring board comprising:a first end curved along the curved surface of the first component and mounted on the curved surface;
a second end mounted on the flat surface of the second component; and
a middle portion extending from the first end to the second end, the middle portion including:
a flat section about perpendicular to the flat surface of the second component; and
a folded section folded to project from a back surface of the flat section at a boundary between the middle portion and the first end adjacent to an edge of the curved surface of the first component, the folded section including a first base curved along the first end and connected with the first end, a second base connected with the flat portion, and a distal end between the first base and second end and farther from the back surface of the flat section than the first base and the second base.
