Abstract: The present invention provides an SPR sensor cell having very excellent detection sensitivity, the SPR sensor cell including: an under-cladding layer; a core layer formed so that at least a part of the core layer is adjacent to the under-cladding layer; and a metal layer covering the core layer. In the SPR sensor cell, the core layer includes a uniform refractive index layer and a graded refractive index layer. The graded refractive index layer is arranged between the uniform refractive index layer and the metal layer. A refractive index of the graded refractive index layer is equal to or more than a refractive index of the uniform refractive index layer, and the refractive index of the graded refractive index layer increases continuously from a surface thereof on a uniform refractive index layer side to the metal layer side in a thickness direction of the graded refractive index layer.
