Multilayer electronic component and method for manufacturing multilayer electronic component
A multilayer electronic component having a plurality of stacked dielectric layers and a plurality of internal electrode layers. Each of the dielectric layers has a plurality of crystal grains including a perovskite-type compound containing Ba, a first rare earth element and a second rare earth element. A difference between a positive trivalent ion radius of the first rare earth element and a positive divalent ion radius of Ba is smaller than a difference between a positive trivalent ion radius of the second rare earth element and the positive divalent ion radius of Ba. A sum of an amount of the first rare earth element and the second rare earth element in a first region along a grain boundary is larger than a sum of an amount of the first rare earth element and the second rare earth element in a second region in a center portion of the crystal grain.
