Abstract
The present invention provides a detecting element which can stably detect a substance with high sensitivity; a detecting device therefor; and a detecting method therefor. The detecting element and the detecting device according to the present invention have a plurality of planes having a plurality of mutually-separated metallic structures arranged thereon. The detecting method according to the present invention includes making a detecting light irradiate the detecting element so that the light can intersect a plurality of the planes. Thereby, the detecting light is more frequently absorbed in the vicinity of the metallic structure and the detecting device can stably detect a slight change of a spectrum originating from a trace change of a refractive index occurring in the vicinity of the metallic structure, with the high sensitivity.
