Abstract
In a localized surface plasmon detection system using a metal thin film pattern, by radiating light for detection on a detecting element using an effective light source which has a peak out of an axis, the present invention strikes a balance between narrowing a peak width of a spectrum and highly efficient illumination even if it is a case of using converging or diffused light.
