Abstract: PURPOSE: A bulk nano-composite type thermal conduction material and pulverized body, and a manufacturing method thereof are provided to embody quantum confinement effect and phonon glass electron crystal concepts in bulk materials. CONSTITUTION: A bulk nano-composite type thermal conduction material(10) is composed of a grain(13) of thermoelectric materials and a nano metal layer(25) of the grain boundary. The diameter of the grain is 1 to 100micrometes. The nano metal layer is crystallized from amorphous metal having glass transition temperature and crystallization temperature which is lower than a melting point of the thermoelectric materials. The thickness of the nano metal layer is 1 to 50nanometers.
