Patent ID: 8525282

Claim:
A solid-state imaging device, comprising: a substrate internally including a photoelectric conversion unit; and a condensing unit, having a structure giving rise to magnetic resonance, provided on an optical incident side of the substrate, wherein, the structure includes a plurality of metal structures separated in a direction perpendicular to a surface of the substrate, each of the metal structures has a one-dimensionally-extended structure in a direction parallel to the surface of the substrate, each of longitudinal directions of the one-dimensionally-extended structures extends in a same direction, and the one-dimensionally-extended structures are mutually covered along the longitudinal directions thereof, provided that a refractive index of a medium being a region of the optical incident side of the condensing unit is N 1 , a specific permittivity of a medium forming the condensing unit is ∈, and a specific permeability of the medium forming the condensing unit, controlled based on the structure, is μ, relationships of |N 1 |<|√∈×√μ| and 0.63<N 1 /(√∈/√μ)<1.58 are satisfied on an end face of the optical incident side of the condensing unit.
