Abstract
A process for producing an optical element wherein an optical molding is formed by using a mold and thereafter released from the mold by supplying a gas to the boundary between the mold surface and the optical molding. In the process, no localized external force is applied to the optical molding during the release thereof, and therefore undesirable deformation or flaws of the optical molding are not caused.
