Abstract: According to the present invention, there is provided a light scattering type particle detector in which the S/N ratio is improved. In the light scattering type particle detector, a particle detecting region D is formed by irradiating laser light La on sample fluid and scattering light Ls due to particles which pass through the particle detecting region D is received with the light receiving array 5. The light receiving array 5 is formed to be circular by arranging a plurality of photoelectric converters Pd1-Pdn in a plane alignment. The adder 6 adds the output from the plurality of the photoelectric converters Pd1-Pdn.
