A thermoelectric material having a high Seeback coefficient and a large power 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. Embodiments of the combination of the laminar bodies are Bi&mdash;Al, Bi-polyamide series resin, and Ag&mdash;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.

Diamond powder is produced without using an ultra-high pressure apparatus by a process comprising melting carbon and a metal capable of dissolving carbon to form a liquid, subjecting the liquid to quenching at an ultra-high cooling rate to form an amorphous metal, heating the amorphous metal at a predetermined temperature to precipitate diamond crystals from the amorphous metal and then separating the phase of the amorphous metal other than the diamond to obtain diamond powder.
