    Abstract: A multilayer ceramic electronic device comprising a lamination in which an internal electrode layer 3 and a dielectric layer 2 are laminated alternatively, wherein the dielectric layer 2 is comprised of a dielectric ceramic composition including a main component represented by a general formula of ABO3 and a rare-earth component R, and segregation phases 5 including the rare-earth component R are present in the dielectric layer 2. When the dielectric layer 2 is separated to six areas by dividing the dielectric layer 2 sandwiched by a pair of the internal dielectric layers 3 in the thickness direction, there are the R segregation phases present in two neighboring areas 2a respectively adjacent to the pair of the internal electrode layers 3 in the dielectric layer 3 at a ratio of double or more compared with the R segregation phases present in two central areas 2b located at a substantially center in the dielectric layer 2.

    Abstract: A package includes a storage portion that stores an object to be stored, and a buffer portion that reduces a gap generated between the object to be stored and the storage portion. The storage portion includes a bottom and a lid facing the bottom, and the buffer portion includes a base facing the object to be stored in a stacking direction from the bottom toward the lid, a first fold, and a space adjusting portion connected to the base at the first fold. The space adjusting portion includes an adjusting region extending in the stacking direction, a plurality of second folds distributed in a first direction intersecting the first fold, and a contact region connected to the adjusting region at one of the plurality of second folds.
