Abstract: An optical unit with a shake correction function includes a movable module and a fixed body. The movable module has a lens and is supported by the fixed body to be capable of moving in a direction orthogonal to an optical axis of the lens. The fixed body surrounds the movable module from an outer periphery side. The movable module includes a first substrate and a second substrate, with a thickness direction of either substrate being consistent with the direction along the optical axis. An image sensor is disposed on the first substrate. The second substrate is electrically connected to the first substrate to overlap the first substrate on an image side, and is smaller in shape than the first substrate when viewed along the optical axis of the lens. A flexible printed circuit board is led out from an outer circumferential surface of the second substrate.
