Abstract:
An electronic device includes a chip component with a terminal electrode formed on an end surface of a ceramic element body including an internal electrode and an external terminal electrically connected to the terminal electrode. The external terminal includes a terminal electrode connection part arranged to face the terminal electrode and a mounting connection part connectable to a mounting surface. The terminal electrode connection part includes a multilayer structure of a first metal connected to the terminal electrode, a second metal arranged outside the first metal, and a third metal arranged outside the second metal. A thermal expansion coefficient of the external terminal is smaller than that of the ceramic element body.
