The invention provides a manufacturing method of a multilayer capacitor. A plurality of capacitor layers are formed by forming a first electrode, a second electrode and a dielectric layer of the multilayer capacitor, the size of the capacitor is reduced, a medium layer is further formed to wrap the multilayer capacitor, an etching method is used to etch the first electrode on one side of a laminating body, so that the first electrode on the side of the laminating body is shorter than the second electrode, the etching method is used to etch the second electrode on the other side of the laminating body, so that the second electrode on the side of the laminating body is shorter than the first electrode, etching a plurality of grooves and using more masking layers are avoided, the process is simplified, and the performance of the device of the multilayer capacitor is improved.
