PROBLEM TO BE SOLVED: To improve an S/N ratio, to heighten a peak of irradiation light, and to prolong a life of a light source. SOLUTION: In this particle detector for guiding a fluid of a detecting object to a particle detecting area 8 formed by irradiation of light to detect a particle contained in the fluid, a pulse like laser beam La is used as the light for forming the particle detecting area 8.
