The present invention provides a measuring device for three-dimensional electric field distribution, which includes three groups of transmitting electrodes and a pair of test electrodes. The three groups of transmitting electrodes are respectively fixed on three mutually orthogonal planes. Each group of transmitting electrodes consists of two pairs of electrodes, and two sinusoidal alternating current signals in the kilohertz range with slightly different frequencies are introduced, forming a phase interference electric field in the three-dimensional space between the two pairs of electrodes. During measurement, the three groups of transmitting electrodes alternately output electrical signals in sequence, which is equivalent to rotating the transmitting electrodes. The test electrodes can move arbitrarily in space. When each group of transmitting electrodes works, the electric field intensity components of each point in space in the corresponding direction can be measured; after the three groups of transmitting electrodes work alternately, the electric field intensities in three directions can be measured. The feature of the present invention is that only a pair of test electrodes are used, and by using the equivalent rotation of the transmitting electrodes, the electric field intensities in three directions at each point in space can be obtained. This measuring device can be used to measure the electric field intensities in the three directions of the X, Y, and Z axes at each point of the phase interference electric field.
