PROBLEM TO BE SOLVED: To provide a particle detector for detecting biogenic particles with high sensitivity.SOLUTION: The particle detector includes a collecting member 10 for electrostatically collecting particle on a main surface thereof, a radiation unit 21 for radiating excitation light to the particles collected on the main surface, a light receiving unit 34 for receiving fluorescence light emitted by the particles by radiation of the excitation light to the particles, a detection unit for detecting biogenic particles from among the particles collected on the main surface on the basis of intensity of the fluorescence light on the light receiving unit, and a filter 37 which is arranged between the main surface and the light receiving unit and cuts off light of a wavelength emitted, by radiation of the excitation light, from the substances generated at electrostatic collection on the main surface. |
