Abstract: A ceramic electronic device includes multiple chip components and a pair of metal terminal portions. The chip components consist of a pair of chip end surfaces and four chip side surfaces. Terminal electrodes are formed on the pair of chip end surfaces. The pair of metal terminal portions is arranged correspondingly with the pair of chip end surfaces. Each of the pair of metal terminal portions includes an electrode face portion, a pair of engagement arm portions, and a mount portion. The electrode face portion faces the chip end surface. The pair of engagement arm portions sandwich and hold the chip component. The mount portion extends from one of terminal second sides toward the chip component and is partially substantially vertical to the electrode face portion. The electrode face portion has a slit.

Abstract: A method of manufacturing an electronic device includes preparing a chip component with a terminal electrode. A terminal plate is prepared. A connection member is placed between an end surface of the terminal electrode and an inner surface of the terminal plate. The terminal plate and the terminal electrode are joined using the connection member by bringing a press head into contact with an outer surface of the terminal plate and pressing and heating the terminal plate against the terminal electrode.
