Abstract: The present disclosure relates to a microbial concentration detection element in an unknown solution. In more detail, the microbial concentration detection element includes: a preprocessing unit configured to produce a microbe substitution solution by transferring microbes in an unknown solution containing detection target microbes into a reference solution through acoustophoresis, and to calculate electrical property information of the microbe substitution solution; and a microbe concentration measurement unit configured to separate the microbe substitution solution into a microbe concentration solution and a filtered solution through dielectrophoresis on the basis of the electrical property information measured by the preprocessing unit, and then measure a microbial concentration of the microbe concentration solution.
