Abstract
A ceramic electronic device includes a ceramic element body, a terminal electrode, and a lead terminal. The ceramic element body has an end surface and a lateral surface. The terminal electrode is formed on from the end surface to a part of the lateral surface of the ceramic element body. The lead terminal is connected to the terminal electrode by a connection member. The lead terminal includes an electrode facing portion disposed correspondingly to an end-surface electrode of the terminal electrode, an extension portion extending downward from a lower end of the electrode facing portion, and a step surface located between the electrode facing portion and the extension portion. The electrode facing portion has a first recess facing the terminal electrode. A part of the first recess reaches the step surface. Another part of the first recess is open outside the lead terminal.
