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 NCO of the uniform layer satisfies a relationship of 1.34≦NCO<1.44; a refractive index NCL of the under-cladding layer and the refractive index NCO of the uniform layer satisfy a relationship of NCO−NCL≧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 NCL to less than the NCO.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
