Abstract
There are provided an SPR sensor cell and sensor, both having very excellent detection sensitivity. The SPR sensor cell includes: an under-cladding layer; a core layer, at least a part of the core layer being adjacent to the under-cladding layer; and a metal layer covering the core layer. The core layer includes a uniform layer and a gradient layer arranged between the uniform layer and the under-cladding layer; a refractive index Nof the uniform layer satisfies a relationship of 1.34≦N<1.44; a refractive index Nof the under-cladding layer and the refractive index Nof the uniform layer satisfy a relationship of N−N≧0.020; and a refractive index of the gradient layer gradually increases from an under-cladding layer side to a uniform layer side in a thickness direction of the gradient layer within a range of from more than the Nto less than the N.
