A multilayer electronic device includes an element body including an interior region and an exterior region and a pair of external electrodes. The interior region includes inner dielectric layers and internal electrode layers laminated alternately. The exterior region is disposed outwards from the interior region in a lamination direction. The pair of external electrodes is disposed on a surface of the element body and connected to the internal electrode layers. D<D<Dand D>D>Dare satisfied, where 'RA' includes an element having a highest mole ratio among “RE” in the inner dielectric layers of a third region at a center of the interior region in the lamination direction, “RB” includes an element having a highest mole ratio among “RE” in a first region at a center of the exterior region in the lamination direction, and “RA” and “RB” are different from each other.
