Abstract
In an optical element, an optically transparent substance is sandwiched between transparent paired plate-shaped elements by utilizing a connection member capable of deforming, and the angle formed by the paired plate-shaped elements is caused to vary by a force applied thereto from the outside, so that a predetermined optical characteristic for the passing light rays is obtained. The connection member is constructed from a high-molecular material capable of molding.
