Electronic device and connecting component

A connecting component, comprising:

• a base material having a plurality of surfaces, wherein
• the plurality of surfaces includes at least a first surface and a second surface,
• the second surface is opposite to the first surface,
• the connecting component is to be arranged between a first substrate portion and a second substrate portion that faces the first substrate portion;
• a plurality of potential wirings inside the base material, wherein
• the plurality of potential wirings has an arbitrary potential,
• the plurality of potential wirings includes a plurality of electrodes,
• an electrode of the plurality of electrodes is at a corner of the base material, and
• the electrode is exposed from three surfaces of the plurality of surfaces;
• and
• a plurality of signal wirings inside the base material, wherein
• the plurality of signal wirings is configured to receive a specific signal,
• a first end of the plurality of potential wirings and a first end of the plurality of signal wirings are respectively exposed from the first surface, and
• a second end of the plurality of potential wirings and a second end of the plurality of signal wirings are respectively exposed from the second surface.
