    摘要: An electronic device includes an electronic element, a plurality of first sub-electrodes arrayed in a first direction, a plurality of second sub-electrodes arrayed in a second direction that is orthogonal to the first direction, a dummy electrode, and a sealing resin. The sealing resin has a resin back surface from which the plurality of first sub-electrodes, the plurality of second sub-electrodes and the dummy electrode are exposed. The plurality of second sub-electrodes are located further in the first direction than any of the plurality of first sub-electrodes. The plurality of first sub-electrodes are located further in the second direction than any of the plurality of second sub-electrodes. The dummy electrode is located further in the first direction than any of the plurality of first sub-electrodes, and is located further in the second direction than any of the plurality of second sub-electrodes.
