Abstract:
1. A method for producing a multilayer ceramic electronic, the method comprising the steps of: forming a raw electronic component aggregate having a structure including a plurality of ceramic green sheets which are stacked on each other, the raw electronic component aggregate having a plurality of joining via hole conductors which define a plurality of joining electrodes provided thereat; exposing the joining via hole conductors at portions of inside surfaces defining corresponding through holes by forming the through holes at locations of the raw electronic component aggregate that divide the joining via hole conductors, the through holes passing through opposing first and second major surfaces of the raw electronic component aggregate; baking the raw electronic component aggregate; dividing the electronic component aggregate along a division line passing through the through holes in order to provide a plurality of electronic component bodies having the joining electrodes, formed by dividing the corresponding joining via hole conductors, formed on portions of a plurality of inside surfaces of a plurality of notches formed by dividing the through holes; mounting a plurality of components onto a plurality of first major surfaces of the electronic component bodies; securing a plurality of covers to the corresponding electronic component bodies by arranging the covers so as to cover the corresponding components with a plurality of openings of the covers facing the corresponding electronic component bodies, by positioning a plurality of legs inside the corresponding notches, and by joining the legs to the corresponding joining electrodes; and forming a plurality of external terminal electrodes onto a major surface of the ceramic green sheet defining the second major surface of the electronic component aggregate or the second major surface of the electronic component aggregate.
