Abstract
Method of manufacturing an optical element capable of providing a satisfactory shape accuracy even where a plurality of optical elements are molded. By providing a protruding portionto change the flow of molten glass drop GD for an optical element with a forming mold, it is possible to make the glass drop GD for an optical element flow along an optical surface transferring surfacein the vicinity of edge side close to the drop point of the glass drop GD for an optical element, among the optical surface transferring surfaces. According to this, even where a plurality of glass lensesare collectively molded, it is possible to transfer an optical function surfaceof the glass lensto each optical surface transferring surfacewith a high accuracy and to collectively manufacture the glass lenseswith a satisfactory shape accuracy.
