    • A chemical sensor element contains a resonator having a first reflector in which particles of a fine metal structure are arranged two-dimensionally and periodically is counterposed with interposition of a dielectric layer to a second reflector, wherein the resonance wavelength of a resonator in which the entire of the first reflector is replaced by a metal thin film having the same thickness as the metal fine structure is different from the surface plasmon resonance wavelength induced in the metal fine structure; and the mode of the surface plasmon resonance excited in the metal fine structure is coupled with the mode of the resonator in which the entire of the first reflector is replaced by the metal thin film.
    • 化学传感器元件包括具有第一反射器的谐振器,其中精细金属结构的颗粒被二维地周期性布置,并且与第二反射器插入电介质层,其中整个谐振器的谐振波长 由具有与金属精细结构相同的厚度的金属薄膜替换为与金属精细结构中诱发的表面等离子体共振波长不同的金属薄膜; 并且在金属精细结构中激发的表面等离子体激元谐振的模式与谐振器的模式耦合,其中整个第一反射器被金属薄膜代替。
