Abstract:
1. An optical part manufacturing method comprising: a deformation step of bringing a molding material and a transfer body having a transfer element including an optical element forming part to form an optical element in the molding material and projection forming parts to form projections in positions apart from a position where the optical element is formed in the molding material during one said deformation step, the deformation step forming the projections extending from the optical part, which come in direct contact with a surface of a bonded part, the surface facing the optical element, the optical element forming part and the projection forming parts being arranged on a planar surface of the transfer element and spaced apart from each other on said surface of the transfer element and defining a profile of the transfer element, and the projection forming parts being generally circular recesses disposed at even intervals around the optical element forming part, and deforming the molding material to copy a counter profile of the profile of the transfer element; a hardening step of hardening at least a deformed area of the molding material; and a detaching step of detaching the molding material and the transfer body from each other, wherein a transfer step of transferring the profile of the transfer element to the molding material is repeated a plurality of times to manufacture an optical part.
