Abstract
A optical device including conductive films having a first and second surfaces, one hole, surface specific shapes periodically, and a layer inserted as an intermediate layer between the first and the second surface of conductive films. The intermediate layer has the effect for improving surface roughness of the surface of conductive film. A light incident upon one surface enhances an intensity transmitted though the hole.
