A fluorescence imaging device includes a microplate that holds a plurality of samples generating fluorescence, a lens assembly, and an imaging unit that collectively images the plurality of samples through the lens assembly. The lens assembly includes a Fresnel lens made of a resin, a second protective plate that protects the surface of the Fresnel lens facing the microplate, a spacer that forms a gap between the Fresnel lens and the protective plate, and a frame by which the Fresnel lens, the second protective plate, and the spacer are sandwiched.
