The invention discloses a preparation method of a multilayer ceramic capacitor. The invention sinters the sintered block and the laminated body, volatilizes the sintering auxiliary agent in the sintered block so as to form a local atmosphere with high volatilization concentration around the laminated body, effectively prevents the excessive volatilization of the sintering auxiliary agent in the laminated body, and makes the sintered ceramic body uniform, compact and consistent. The surface of the sintered block adopted by the invention is provided with a nickel layer, so that adhesion betweenthe sintered ceramic body and the sintered block can be avoided. The ceramic body prepared by the invention is uniform and compact, has good consistency, does not adhere to the sintered block, and iseasy to screen with the sintered block.
