An n-type thermoelectric conversion material that has a high Seebeck coefficient, a low electric resistivity, and a large power factor includes, as its main constituent, a metal material mainly containing Ni, and includes an oxide material containing Sr, Ti, and a rare-earth element in the range of about 10 wt % to about 30 wt %. The oxide material is a SrTiO3 based oxide material. For producing the thermoelectric conversion material, through the steps of mixing and grinding a SrTiO3 based oxide material and a Ni metal powder to prepare a mixture, forming this mixture into a shape to prepare a compact, and then firing the compact, the thermoelectric conversion material is obtained.
