PROBLEM TO BE SOLVED: To provide a microorganism number measurement apparatus with which a person for measuring microorganisms can specify such a measurement method as satisfying preliminarily requiring measurement sensitivity and measurement time and which realizes microorganism number measurement fit to an object, and to provide a microorganism number measurement method. SOLUTION: This microorganism number measurement apparatus is characterized by comprising a cell which has electrodes therein and into which a liquid containing microorganisms can be introduced, a migration electric source circuit, a measurement portion for measuring impedances caused by microorganisms gathered between the electrodes, an operation portion for operating the initial inclination of an impedance time change caused by the gathering of the microorganisms between the electrodes from the measurement result of the measurement portion, thus calculating the number of the microorganisms, a control portion, and a plurality of input means, wherein the control means changes a measurement time in response to commands inputted with the input means.
