Dielectric composition, dielectric element, electronic device, and multilayer electronic device

Abstract

A dielectric composition includes a dielectric grain. The dielectric grain includes a core portion and a shell portion. The core portion contains a first perovskite oxide as a main component. The shell portion contains the first perovskite oxide and a second perovskite oxide as a main component. The second perovskite oxide has a composition different from that of the first perovskite oxide. The first perovskite oxide contains at least one selected from the group consisting of Ba, Sr, and Ca at the A-site and at least one selected from the group consisting of Ti and Zr at the B-site. The second perovskite oxide contains at least one selected from the group consisting of Ba, Sr, and Ca at the A-site and at least one selected from the group consisting of Ti and Zr at the B-site.
