Abstract:
The problem addressed lies in providing a dielectric composition which is advantageously used in a power supply circuit having a high rated voltage, and has high DC bias resistivity and a high dielectric constant when a DC bias is applied, and also has a favourable high-temperature load lifespan; and also in providing a dielectric element employing said dielectric composition, an electronic component and a laminated electronic component. [Solution] A dielectric composition comprising particles having a perovskite crystal structure including at least Bi, Na, Sr and Ti. At least some of the particles have a core-shell structure comprising a core portion and a shell portion. The content of Bi present in the core portion is no greater than 0.83 times the content of Bi present in the shell portion.
