ABSTRACT:
A dielectric element having a dielectric layer provided between an upper electrode layer and a lower electrode layer, wherein the dielectric layer has a first dielectric layer and a second dielectric layer mutually different in composition, and composition of at least one component of the first dielectric layer changes as to a thickness direction of the first dielectric layer in proximity to a boundary between the first dielectric layer and the second dielectric layer.
