<p>Provided are a high NA lens having no defects caused when it is molded and a molding die which can be used to mold such a lens. As a lens (OE) has a first end area (OE11b) and a second end area (OE21b) which does not overlap the first end area when viewed along the optical axis direction, the surface area of a restricted portion which is most restricted in the molding die is reduced, so that the resistance of a resin during an injection molding can be reduced. Consequently, it is possible to prevent the occurrence of striae in a first optical surface (OE11a).</p> |
