A method for making a holder/optical-element assembly includes the steps of positioning a cylindrical holder material in a press-molding die, the holder material having a void part in the inner circumferential surface, positioning an optical-element material inside the holder material, heating the holder material and the optical-element material to their own softening temperatures, press-molding the holder material and the optical-element material to form a cylindrical holder and an optical element, respectively, thereby fixing the optical element to the inside of the holder, allowing a part of the optical element to project outwardly from the outer edge by pressure created during press-molding, and retaining the projected portion in the void part of the holder.
