1. An image pickup unit comprising:
a printed wiring board provided with an image pickup element and having a first electrode on a primary face of the printed wiring board;
a flexible wiring substrate having a base member having a first face and a second face, a conductive layer provided on the base member on a side of the first face, and an insulating layer provided on the conductive layer, wherein the conductive layer has a first region between the base member and the insulating layer, and the conductive layer further has a second electrode which is not provided between the base member and the insulating layer;
a conductive connection member that connects the first electrode to the second electrode, the conductive connection member contacts a second region of the second electrode; and
a reinforcement member provided on the base member on a side of the second face,
wherein the reinforcement member continuously covers a first portion of the flexible wiring substrate and a second portion of the flexible wiring substrate, the first portion including the second region of the second electrode, and the second portion including the first region of the conductive layer,
wherein the second portion is arranged above the primary face of the printed wiring board, and the second portion is bent to a direction away from the printed wiring board with respect to the first portion.
