The conventional dielectric measurement method utilizes an interaction between a uniform electric field and a dipole moment, and hence a motion of nonpolar molecules without the dipole moments cannot be detected. It is an object of the present invention to provide a method for electrically detecting the motion of the nonpolar molecule. According to the present invention, the motion of the nonpolar molecule is detected electrically by utilizing a nonuniform electric field in dielectric measurement. As a specific measurement method, comb-shaped electrodes or electrodes with irregularities on their surfaces are employed in the dielectric measurement in place of conventional parallel flat-plate electrodes. By utilizing the interaction between the nonuniform electric field generated by these electrodes and a quadrupole moment or a high-order electric moment, it has become possible to electrically detect the motion of the nonpolar molecule.
