The invention belongs to the fields of atom, molecule and quantum optics, and in particular relates to a multi-purpose electric field generating device used for ultracold molecule manipulation. The multi-purpose electric field generating device used for the ultracold polar molecule manipulation comprises four cylindrical copper electrodes, each cylindrical copper electrode has a diameter of 3 mm and a length of 30 mm, the front end surface of each cylindrical copper electrode is located in a same plane, the rear end surface of each cylindrical copper electrode is located in a same plane, centers of cross-sectional circles of the four cylindrical copper electrodes form a rectangle having a long edge of 12.16 mm and a short edge of 6 mm, and the distance between the center of a cross-sectional circle of a first cylindrical copper electrode and the center of a cross-sectional circle of a second cylindrical copper electrode is 6 mm. The device provided by the invention can generate a high-uniformity electric field in a region of 100 [mu]m x 100 [mu]m x 100 [mu]m.
