Abstract
An optical element such as a lens is produced in a manner that a resin is supplied to a mold member having a transfer face for forming an optically functional face, a glass blank is placed on the resin, and a curing energy is irradiated to the resin so as to be uniformly incident on the resin, thereby preventing stress being nonuniformly distributed or shrinkage on the resin surface upon curing.
