Abstract
A lens includes a lens body, and an electro-active section (liquid crystals and a diffraction section) that is provided to a region of part of the lens body. The lens includes a pair of electrodes that are embedded in the lens body, that are electrically connected to a focal length modification section, that extend downward from an upper side end of the lens body, and that are disposed substantially parallel to each other spaced apart in a width direction orthogonal to an up-down direction of the lens body. Lower ends of the pair of electrodes are disposed spaced apart from the electro-active section in the up-down direction of the lens body.
