Abstract
An optical near-field generating apparatus includes a conductive scatterer causing an optical near-field based on a surface plasmon to be generated by being illuminated by incident light, and a conductive body arranged in a vicinity of the scatterer and generating a surface plasmon by being illuminated by the incident light and by being influenced by the surface plasmon of the scatterer. An oscillation direction of the surface plasmon of the conductive body is approximately parallel to an oscillation direction of the surface plasmon of the scatterer, and a generation region of the surface plasmon of the conductive body exists in a position deviated from a region extending in an oscillation direction of the surface plasmon of the scatterer.
