| 摘要 |
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 lambda (nm), the periodicity of the periodic structure is (lambda/633)x100 nm to (lambda/633)x500 nm, and the amplitude of the periodic structure is (lambda/633)x5 nm to (lambda/633)x20 nm. For example, when lambda=633 nm, the periodicity of the periodic structure is 100 nm to 500 nm, and the amplitude is 5 nm to 20 nm.
