A sensor chip includes: a transparent support; a metal thin film formed on one surface of the transparent support; and a reaction section in which a ligand is immobilized on an other surface of the metal thin film that is not in contact with the transparent support, wherein the sensor chip also includes a closed space-forming member which forms a closed space such that at least the reaction section is housed in the closed space, and water content in the closed space is adjusted to satisfy: X/Y&#x3c;10 (&#x3bc;g/mm) (wherein, X represents the water content in the closed space; and Y represents the surface area of the metal thin film in the closed space).

Sensor chip and method for storing sensor chip

[Object] It is an object of the invention to provide a sensor area which can suppress a decrease in assay signal and an increase in assay blank in an SPFS measurement. [Solution] An SPFS sensor chip of the invention includes a purification area and a sensor area arranged upstream and downstream, respectively, relative to each other along a flow direction in a channel for surface plasmon-field enhanced fluorescence spectroscopy [SPFS].
