An image pickup apparatus of the present invention includes: a lens holding frame 10 that holds a lens 30, on the periphery of which a first pair of restricting members composed of convex members 101 and 102 are provided at at least two places; and a circuit board 20 that connects the lens holding frame 10 with a camera main body electrically. The circuit board 20 includes a flexible substrate 21 with wiring that establishes electrical connection, and a reinforcing plate 22 fixed to a part of the flexible substrate 21. The circuit board 20 is fixed to the lens holding frame 10, such that at least a part of the reinforcing plate 22 is disposed between the first pair of restricting members, and that both ends of the part of the reinforcing plate 22 disposed between the first pair of restricting members are restricted by the first pair of restricting members. Consequently, it is possible to provide a camera that is easy to manufacture or to provide a camera that causes little flare.
