Electronic part, electronic device, and electronic apparatus

An electronic device comprising:

• a first electronic part including:
• a substrate;
• an insulating film formed over the substrate, having a first region including a first opening portion and a first peripheral portion of the first opening portion, and having a second region including a second opening portion whose opening area is larger than an opening area of the first opening portion;
• a first pillar electrode formed over the first region;
• and
• a second pillar electrode formed over the second region;
• a second electronic part disposed opposite the first electronic part and including a first terminal formed at a position corresponding to the first pillar electrode and a second terminal formed at a position corresponding to the second pillar electrode;
• a first solder formed between the first pillar electrode and the first terminal;
• and
• a second solder formed between the second pillar electrode and the second terminal.
