Abstract
Provided is an SPR sensor which can achieve compaction and multichannel detection by simple configuration at a low cost. The SPR sensor comprises an optical path, and detection areas on the side surface thereof formed by laminating metal layers formed to cause surface plasmon resonance phenomenon. The SPR sensor is characterized in that two or more detection areas are formed for one optical path, a dielectric constant regulation layer is further laminated in at least one of the two or more detection areas, dielectric constant is regulated to have a different surface plasmon resonance in each detection area, and a dielectric constant regulation layer laminated in the at least one of the two or more detection areas functions as a layer exhibiting sensitivity to an object to be detected.
