A fluorescence detection device includes a flow cell body including a flow channel through which a measurement object flows, a laser light source unit that irradiates, with a laser beam, the measurement object passing through a measurement point in the flow channel, a light-receiving unit that receives fluorescence emitted from the measurement object irradiated with the laser beam and outputs a light-reception signal, and a processing unit that outputs an output value of fluorescence intensity based on the light-reception signal outputted by the light-receiving unit. The flow cell body has a lens provided on a surface thereof so as to traverse an optical path of the laser beam. |
