A virus in the atmosphere can be precisely detected on a real time basis. At a main pipeline 8, a dust removing unit 1, an atomization unit 4, a fluorescence measuring unit 5 in which a laser beam is irradiated, and a suction pump 7 are arranged in this order, and a suctioned air current is generated in the main pipeline 8 through the suction pump 7. Meanwhile, a diffusion unit 3 includes a liquid flow path 35 and a gas flow path 34 formed in parallel to the liquid flow path, and an atmosphere and an aqueous solution containing a fluorescent antibody F pass through the gas flow path 34 and the liquid flow path 35, respectively. The aqueous solution is flown into the atomization unit 4 through a guide passage 40 branched from a branch part that is formed at an outlet side of the flow paths 34 and 35 and discharges the gas and the aqueous solution after separating the gas and the aqueous solution. A mist group is flown into the fluorescence measuring unit 5. Since a fluorescence intensity of the mist M when the virus V exists is higher than a fluorescence intensity when no virus V exists, the virus V can be detected by monitoring the fluorescence intensity. |
