Abstract: A particle detection apparatus includes a plurality of photodetectors that detect reaction light generated at a particle irradiated with inspection light and generate electric signals in respective channels; pulse detectors that detect pulses of the electric signals in the respective channels; a correlating unit that correlates the pulse of the electric signal in a reference channel being a channel having a highest signal-to-noise (S/N) ratio, with the pulse of the electric signal in a channel other than the reference channel generated within a predetermined time difference range with respect to the pulse of the electric signal in the reference channel; and an attribute specifying unit that specifies an attribute of the particle on the basis of the correlated pulses of the electric signals.
