<p>Provided are an SPR sensor cell having very excellent detection sensitivity and an SPR sensor. The SPR sensor cell includes a detection unit; and a sample mounting portion adjacent to the detection unit, wherein: the detection unit includes an under clad layer, a core layer formed so that at least a part thereof is adjacent to the under clad layer, a metal layer covering the core layer, and a coat layer covering the metal layer; the coat layer is formed of a material having a band gap (Eg) of more than 1.0 eV and less than 7.0 eV; and a refractive index of the coat layer is higher than a refractive index of the core layer.</p> |
