1. An image pickup unit comprising:
an image pickup optical system including an optical axis;
an image pickup device configured to pick up an optical image formed by the image pickup optical system;
a first electric substrate on which the image pickup device is mounted;
a second electric substrate configured of a component formed integrally with the first electric substrate, the second electric substrate being configured to surround peripheries of the image pickup optical system and the image pickup device and extend in a direction along the optical axis, the second electric substrate including a housing space for housing the image pickup optical system and the image pickup device, an inside of the housing space having a quadrangular prism shape, at least a part of the second electric substrate being formed in an arc shape when viewed in a cross section in a vertical direction with respect to the optical axis; and
a conductive circuit configured to connect the first electric substrate and the second electric substrate, the conductive circuit being provided continuously from a first surface to a second surface of the second electric substrate, the first surface being exposed outside, the second surface facing the periphery of the image pickup optical system in the housing space.
