Abstract: A measurement device according to one embodiment of the present invention, comprises: a voltage applying part for applying a voltage between electrodes of a biosensor, the biosensor comprising a solid electrolyte and at least two electrodes, and being configured such that the solid electrolyte and the electrodes are in contact with each other; a detection part for measuring a current value flowing between the electrodes when the voltage is applied; and a computing part for providing information resulting from the microorganisms by comparing the current value with a reference value stored in advance in which a current value and at least one type of factor selected from the group consisting of the presence or absence of the biological particles, a proliferative state of the microorganisms, and the presence or absence of expression of pathogenicity of the microorganisms are defined.
