OPTICAL ELEMENT AND OPTICAL PICKUP DEVICE

摘要

Provided are an optical element and an optical pickup device which can prevent lowering of the optical performance caused by a fluorination process.  The optical element has a molded portion molded by a resin material.  The resin material contains a resin having an alicyclic hydrocarbon structure, wherein each unit structure has three or less tertiary carbon atoms.  The molded portion has, on the surface thereof, a layer containing a resin having the alicyclic hydrocarbon structure in which at least one hydrogen atom is replaced by a fluorine atom.
