Abstract
A fluorescence detecting method utilizes surface plasmon enhancement. An electric field enhancing field is caused to be generated at a detecting portion that includes a metal film provided on a surface of a dielectric prism. Fluorescence emitted by fluorescent labels, which are attached to a detection target substance, due to the excitation effect of the electric field enhancing field is detected by a photodetector. During the detection, a plurality of fine metal particles are dispersed on the detecting portion.
