The invention discloses a manufacturing method of a multilayer ceramic capacitor. According to the multilayer ceramic capacitor manufactured in the invention, an organic nanometer protection liquid issprayed on a ceramic film to form an organic nanometer protection layer, and then an internal electrode is printed on the organic nanometer protection layer in a silk-screen mode. By using the multilayer ceramic capacitor, the organic nanometer protection layer can prevent a solvent in an internal electrode slurry from eroding a dielectric film, and prevent increase of a short circuit failure rate and deterioration of reliability of the multilayer ceramic capacitor. Because the organic nanometer protection layer has lower surface energy, the dielectric film can achieve waterproof, solvent-proof, and dust-proof effects, and the increase of the short circuit failure rate and the deterioration of reliability of the multilayer ceramic capacitor can be prevented. The organic nanometer protection layer can increase smoothness of a surface of the dielectric film, reduce a friction coefficient, achieve an anti-static effect, prevent the dielectric film from being upwarped and folded during alamination process, and prevent the increase of the short circuit failure rate of the multilayer ceramic capacitor.
