Abstract: A composite thermoelectric element including thermoelectric sheets each including a facing surface and an exposed surface, which are opposite to each other, and a graphite sheet embedded in the thermoelectric sheets from the facing surfaces thereof. Here, edges of the graphite sheet are separated inward from edges of the thermoelectric sheets such that a contact portion is formed at the facing surfaces of the thermoelectric sheets. Also, the contact portion of the thermoelectric sheets is stuck to one of the objects due to the self stickiness, and the graphite sheet comes in contact with the other of the objects.

The EMI gasket includes an elastic core which includes a first surface and a second surface opposite to each other in a thickness direction and a through hole passing through the first and second surfaces and an electroconductive cover which adheres to the first surface with an adhesive interposed therebetween. Here, parts of the cover which face the through hole are incised to integrally form a plurality of blocking parts, and the blocking parts cover and adhere to sidewalls of the through hole.
