A dielectric element in which a substrate, a lower electrode layer, a dielectric layer and an upper electrode layer are provided in this order, wherein the dielectric layer has a first dielectric layer of which major component is an oxide and provided on a side of said lower electrode layer, and a second dielectric layer of which major component is an oxide and provided on a side of said upper electrode layer, and the second dielectric layer is thicker than the first dielectric layer, and a formula (1): epsilon1/epsilon2 >= 0.9 described below is satisfied when a dielectric constant of the first dielectric layer at 25 DEG C is epsilon1 and a dielectric constant of the second dielectric layer at 25 DEG C is epsilon2. |
