Classification: CPC H | IPC H

Claim 0:
1. A thermoelectric element comprising:
a first substrate;
a first electrode part disposed on the first substrate;
a semiconductor structure disposed on the first electrode part;
a second electrode part disposed on the semiconductor structure; and
a second substrate disposed on the second electrode part,
wherein the second substrate includes a first surface and a second surface opposite to the first surface,
the second electrode part is disposed on the first surface,
a terminal electrode part formed by extending at least one of the second electrode parts is disposed on the second surface, and
the second substrate includes a through hole formed between the terminal electrode part and the second electrode part,
the through hole is formed to extend from one side surface of the second substrate toward the other side surface,
wherein the second substrate further includes a via electrode for forming the terminal electrode part,
wherein the via electrode overlaps the first substrate, and does not overlap the semiconductor structure,
wherein a ratio of a width of the through hole to a distance between the terminal electrode part and the second electrode part closest to the terminal electrode part is 0.4:1 to 0.6:1.
