摘要

A method for manufacturing a magnesium-based thermoelectric conversion material of the present invention includes a raw material-forming step of forming a raw material for sintering by adding silicon oxide in an amount within a range equal to or greater than 0.5 mol% and equal to or smaller than 13.0 mol% to a magnesium-based compound, and a sintering step of heating the raw material for sintering at a temperature within a range equal to or higher than 750°C and equal to or lower than 950°C while applying pressure equal to or higher than 10 MPa to the raw material for sintering so as to form a sintered substance.
