ABSTRACT:
A surface plasmon resonance device of the present invention includes a transparent medium layer and a conductive layer, a periodic structure being present at the interface therebetween. Assuming that the wavelength of visible light incident on the conductive layer through the transparent medium layer is λ (nm), the periodicity of the periodic structure is (λ/633)×100 nm to (λ/633)×500 nm, and the amplitude of the periodic structure is (λ/633)×5 nm to (λ/633)×20 nm. For example, when λ=633 nm, the periodicity of the periodic structure is 100 nm to 500 nm, and the amplitude is 5 nm to 20 nm.
