A fluorescence detection device of the present invention includes a substrate and a light source. A fluorescence enhancement layer of the substrate includes a photonic crystal which is formed from a block copolymer thus in the combination with metal particles or a metal film. An excitation light generated from the light source can illuminate a fluorescent material placed on the fluorescence enhancement layer to induce emission of a fluorescence from the fluorescent material. The fluorescence enhancement layer is provided to enhance luminous efficiency of the fluorescence, thus improving fluorescence detection sensitivity.
