PROBLEM TO BE SOLVED: To provide a hemocyte counter capable of measuring very easily a flow rate of a blood specimen without using a flow sensor or the like, with excellent reproducibility. SOLUTION: In this hemocyte counter provided with a sensor part 1 formed with an aperture 32c in a midway of a flow passage 32 and equipped with two electrodes 33, 34 inside the flow passage 32, wherein the blood specimen S of diluted blood diluted in a diluent liquid is supplied to the sensor part 1 to be moved from the one flow passage 32a to the other flow passage 32b via the aperture 32c, and wherein an impedance change generated when the blood specimen S passes the aperture 32c is detected by the electrodes 33, 34, so as to count the number of hemocytes in the blood based on a detected result, a fixed amount of standard particles 9 of a known particle size is mixed in the blood specimen S, the blood specimen S mixed with the standard particles 9 is supplied to the sensor part 1 to count the number of the standard particles 9, and the flow rate of the blood specimen S is measured based on a counted result therein.
