  • Patent number: 9911535
    Abstract: An electronic device includes a chip component and an external terminal. The external terminal includes a terminal electrode connection part, a mounting connection part, and a support part. The terminal electrode connection part is arranged to face an end surface electrode part of a terminal electrode of the chip component. The mounting connection part is connectable to a mounting surface. The support part faces one side surface of an element body of the chip component closest to the mounting surface so as to support the one side surface spaced from the mounting surface. A bonding region and a non-bonding region are formed between the terminal electrode connection part of the external terminal and the end surface electrode part of the terminal electrode. The non-bonding region is formed from the terminal electrode connection part to the support part.
