The invention provides a real-time no-mark cell analyzer based on the liquid electrical resonance principle. The real-time no-mark cell analyzer is characterized in that the change of a cell culture environment is detected in real time through the change of liquid electric resonance frequency, and thus different states of cell proliferation, cell infiltration, cell migration, cell co-culture and the like are analyzed. The hardware of the cell analyzer is composed of a cell culture dish I comprising specific test electrode chips, an exciting oscillation frequency selection network 2, an equal-precision frequency measurement module 3 and a data communication module 4. Cells are transplanted to the cell culture dish I comprising test electrodes for cell culture, the electric resonance frequency of a cell culture solution is selected through the frequency selection network, the frequency change is accurately measured through the equal-precision frequency measurement module and the measurement result is transmitted to a computer control system through the data communication module, so that real-time recording and analyzing of cell culture can be realized.
