摘要：
Decrease in optical near-field intensity is prevented when an light propagating medium made of a high refractive index material, such as a waveguide or a lens, is combined with a scatterer for producing optical near-field. Near the optical near-field generating element, a second light propagating medium is disposed in contact with a first light propagating medium of a high refractive index material, such as a waveguide or a lens. The refractive index of the second light propagating medium is made smaller than the refractive index of the first light propagating medium.
