| 1. An optical element, comprising:
a pair of substrates each having an electrode, the pair of substrates being bonded together with a gap formed therebetween,
each of the pair of substrates having an electrode connecting portion for connecting the respective substrate to an external
circuit, the electrode connecting portion of each of the substrates being located on the same side of the optical element,
the electrode connecting portion of one of the substrates and the electrode connecting portion of another of the substrates
having respective electrode portions disposed on the side of each of the substrates facing the gap and on regions that are
not opposed to each other the electrode portion of each of the electrode connecting portions being connected to the external
circuit; and
a light adjusting material including a liquid crystal, the light adjusting material being enclosed in the gap.
