The invention relates to a method for efficiently preparing a microelectrode with a large length-diameter ratio and measuring the diameter on line, and belongs to the technical field of electromachining. The method is characterized in that the preparation process of the microelectrode is divided into three steps of removing materials with ultra-large allowance, trimming the shape of the electrode and removing the materials with small amount, and an electrode diameter on-line measuring function is added on the basis of electrode preparation. Wherein in the step 1, an ultra-large allowance removing material is used, and the purpose is to quickly reduce the diameter of an electrode; 2, in order to trim the shape of the electrode, the shape of the electrode machined in the step 1 is corrected, and the electrode precision is improved; and in the step 3, trace removal is conducted on the surface machined in the step 2 again, and the surface quality is improved. After the electrode is prepared, the left side and the
