Beschreibung
Zusammenfassung:	An aspherical lens according to the present invention is provided with an effective lens region having a center region and a surrounding region that surrounds the same. The center region has a wavy shape symmetrical about the optical axis and having a height of 50 nm or less. The surrounding region is smoothly connected to an end part of the wavy shape. A lens unit according to the present invention includes the aspherical lens. A method for manufacturing a lens unit according to the present invention is a method for manufacturing the lens unit that includes the aspherical lens. A lens molding mold according to the present invention has a shape that is the inverse of the aspherical lens. Une lentille asphérique selon la présente invention comporte une région de lentille efficace ayant une région centrale et une région environnante qui entoure cette dernière. La région centrale a une symétrie en forme d'onde autour de l'axe optique et ayant une hauteur de 50 mm au maximum. La région environnante est délicatement reliée à une partie d'extrémité de la forme d'onde. Une unité lenticulaire selon la présente invention comprend la lentille asphérique. Un procédé de fabrication d'unité lenticulaire selon la présente invention est un procédé de fabrication d'unité lenticulaire qui comprend la lentille asphérique. Un moule de moulage de lentille selon la présente invention a une forme qui est l'inverse de la lentille asphérique.
