摘要： Provided is an aspheric lens manufacturing method by which an aspheric lens having a desired shape can be manufactured with high accuracy regardless of the shape of a glass molding without reducing productivity. The aspheric lens manufacturing method for forming the aspheric lens by pressing and machining a glass material includes a pressing step for pressing the glass material to thereby form the aspheric surface, the flat surface of the peripheral portion of the aspheric surface, and the side surface continuous to the flat surface at the same time and form the glass molding, a mounting step for mounting the glass molding in a work holder which holds and positions the glass molding by being in contact with the flat surface and the side surface of the glass molding formed in the pressing step, and a machining step for machining an other surface of the glass molding mounted in the work holder in the mounting step to thereby form the other surface into a predetermined surface shape.
