Abstract
A ceramic electronic device includes a chip component, a metal terminal, and a conductive connection member. The component includes a terminal electrode surface on which a terminal electrode is formed. The metal terminal includes an opposing surface to the electrode surface. The connection member contains at least Sn and Sb and connects the terminal electrode surface and the opposing surface. The connection member includes a first part and a second part. In the first part, a distance between the terminal electrode surface and the opposing surface is a first distance, and Sb/Sn is a first value. In the second part, a distance between the terminal electrode surface and the opposing surface is a second distance being smaller than the first distance, and Sb/Sn is a second value being larger than the first value.
