Abstract: A method for manufacturing a thermoelectric material is provided. According to the method, a first shaped body is formed from a thermoelectric powder, of which a crystal has a layer structure. An extruded body is formed by extruding the first shaped body. A plurality of cut-off pieces are formed by cutting the extruded body along a cross-section perpendicular to an extrusion direction. A second shaped body is formed by stacking and pressing the cut-off pieces along a direction perpendicular to the extrusion direction. According to the above, a thermoelectric ability of a thermoelectric material and an efficiency for manufacturing a thermoelectric module may be improved.
