Electronic device

An electronic device, comprising:

• a circuit board;
• a first element including a first surface and at least a portion of which is joined to a surface of the circuit board;
• and
• a second element including a second surface and at least a portion of which is joined to the surface of the circuit board;
• wherein
• the first element includes a first connection portion including a first recess portion, a third connection portion, a first transmission line portion connecting the first connection portion and the third connection portion to each other, and a plurality of first connection portion side electrodes exposed to the first surface of the first connection portion;
• the second element includes a second connection portion and a plurality of second connection portion side electrodes exposed to the second surface of the second connection portion;
• the circuit board includes a plurality of first board side electrodes, a plurality of second board side electrodes, and a plurality of electrode connection patterns connecting the plurality of first board side electrodes and the plurality of second board side electrodes to each other;
• the plurality of first connection portion side electrodes and the plurality of first board side electrodes are opposed to each other and are each joined with a conductive joining material;
• the plurality of second connection portion side electrodes and the plurality of second board side electrodes are opposed to each other and are each joined with a conductive joining material;
• the plurality of first connection portion side electrodes and the plurality of first board side electrodes are respectively disposed along the first recess portion in plan view of the circuit board;
• and
• the plurality of first board side electrodes and the plurality of second board side electrodes are respectively disposed at positions opposed to each other in plan view of the circuit board.
