Abstract: A thermoelectric material having a high Seebeck coefficient and a large output factor and excellent in shock resistance, thermal strain resistance, and formability, and a thermoelectric element are disclosed. The thermoelectric material and thermoelectric element is composed of a multilayered body made up of a laminar body of a semimetal, a metal, or a synthetic resin and a laminar body of a semimetal. The average thickness of the laminar bodies ranges from 0.3 nm to 1000 nm. Examples of the combination of the laminar bodies are Bi-Al, Bi-polyamide resin, and Ag-Fe. Such a multilayered body is manufactured by forming an initial multilayered body composed of all the types of laminar bodies constituting the multilayered body and rolling or uniaxially pressing a stack of such initial multilayered bodies.
