Flexible wiring structure, flexible wiring method, and imaging device

An imaging device comprising:

• a flexible wiring structure;
• and
• an imaging element that is connected to the flexible wiring structure and images incident light and outputs an imaging signal, wherein
• the flexible wiring structure includes a first flexible wiring section and a second flexible wiring section divided with a relay section provided on one end side of an L-shaped section of a flexible wire having the L-shaped section,
• the first flexible wiring section includes a first raised surface raised from a plane of the relay section via a first relay side bending section provided on the relay section side and a first post-bend raised surface bent in a first bent section, which is a bent section of the L-shaped section, from the first raised surface,
• the second flexible wiring section includes a second raised surface raised from the plane of the relay section via a second relay side bending section provided on the relay section side and a second post-bend raised surface bent in a second bent section, which is a bent section of the L-shaped section and provided above the first bent section, from the second raised surface and parallel to the first post-bend raised surface, and
• the second post-bend raised surface is folded back in a raised surface bending section provided on the second raised surface and overlaps the first post-bend raised surface.

A flexible wiring method comprising:

• forming a first flexible wiring section and a second flexible wiring section divided with a relay section provided on one end side of an L-shaped section of a flexible wire having the L-shaped section;
• forming, in the first flexible wiring section, a first raised surface raised from a plane of the relay section via a first relay side bending section provided on the relay section side and a first post-bend raised surface bent in a first bent section, which is a bent section of the L-shaped section, from the first raised surface;
• forming, in the second flexible wiring section, a second raised surface raised from the plane of the relay section via a second relay side bending section provided on the relay section side and a second post-bend raised surface bent in a second bent section, which is a bent section of the L-shaped section and provided above the first bent section, from the second raised surface and parallel to the first post-bend raised surface;
• and
• folding back the second post-bend raised surface in a raised surface bending section provided on the second raised surface and placing the second-post-bend raised surface on the first post-bend raised surface.
