PROBLEM TO BE SOLVED: To provide a particle detection device capable of accurately detecting a fluorescent particle to be detected.SOLUTION: A particle detection device comprises: a light source 10 which irradiates fluid with excitation light; and a fluorescence intensity measuring instrument 2 which measures intensities of light at at least two wavelengths in a fluorescent band generated in a region irradiated with the excitation light. The light source 10 and the fluorescence intensity measuring instrument 2 are electrically connected to a central processing unit (CPU) 300. The CPU 300 includes a relative value calculation unit 301 which calculates relative values of the intensities of the light measured at the at least two wavelengths. A reference value storage device 351 is electrically connected to the CPU 300. The reference value storage device 351 stores relative values of the intensities of at the at least two wavelengths measured and of the light emitted from a predetermined substance irradiated with the excitation light as reference values. The CPU 300 further includes a determination unit 302 which compares the calculated relative values with the reference values, and determines whether the fluid includes a fluorescent particle to be detected or not. |
