## Abstract

An electronic device includes a plurality of chip components and an external terminal. The chip components are provided with a terminal electrode formed on an end surface of a ceramic element body. The external terminal is electrically connected with the terminal electrodes to support the plurality of chip components adjacently in a first direction. The external terminal includes a terminal electrode connection part arranged to face the terminal electrode and a mounting connection part connectable with a mounting surface. The terminal electrode connection part is provided with a plurality of convex portions protruding toward the terminal electrode. At least one of the plurality of convex portions is respectively connected with each terminal electrode of the plurality of chip components.
