1. A method for producing a multilayer ceramic electronic component that includes a component main body and an outer electrode on an outer surface of the component main body, the component main body including laminated ceramic layers and an internal electrode along an interface between the ceramic layers, and the outer electrode being electrically connected to the internal electrode, the method comprising:
a first stage of producing a green multilayer ceramic electronic component; and
a second stage of producing a sintered multilayer ceramic electronic component from the green multilayer ceramic electronic component; wherein
the first stage includes:
preparing a disappearing ink including a material that disappears by heating, a ceramic-containing ink that is to be fired to form the ceramic layers, a first metal-containing ink that is to be fired to form the internal electrode, and a second metal-containing ink that is to be fired to form the outer electrode;
ejecting the disappearing ink by an ink jet method to form a support that defines at least a portion of a peripheral shape of the green multilayer ceramic electronic component;
ejecting the ceramic-containing ink by the ink jet method to form a green ceramic layer, which is to be one of the ceramic layers;
ejecting the first metal-containing ink by the ink jet method to form a green internal electrode, which is to be the internal electrode; and
ejecting the second metal-containing ink by the ink jet method to form a green outer electrode, which is to be the outer electrode; wherein
the forming the green ceramic layer and the forming the green outer electrode are performed while the support defines at least a portion of a periphery of the green ceramic layer and the green outer electrode, respectively;

in the first stage, the support is formed to include a plurality of layers that are stacked on each other along the peripheral surface of the green multilayer ceramic electronic component; and
the second stage includes:
causing the support to disappear by heating; and
sintering the green multilayer ceramic electronic component.
