A microparticle measuring apparatus and microparticle measuring method which, in sample liquids having different electric conductivities, have a sensitivity and accuracy which are necessary and sufficient, without performing pretreatment of reducing the electric conductivity are provided. The microparticle measuring apparatus includes: a cell 1 into which a liquid containing microparticles is to be introduced; at least one pair of electrodes which are immersed in the cell 1; a migration power supply unit 4 which applies an AC voltage of a frequency at which a dielectrophoretic force on the microparticles is equal to or larger than a predetermined value, between the pair of electrodes; a measurement unit 5 which measures the microparticles in the cell; and a control calculation unit 6 which calculates a result of the measurement performed by the measurement unit, and which calculates the concentration of the microparticles in the liquid. |
