Abstract
A magnesium-based thermoelectric conversion material made of a sintered compact of a magnesium compound, in which, in a cross section of the sintered compact, a Si-rich metallic phase having a higher Si concentration than in magnesium compound grains is unevenly distributed in a crystal grain boundary between the magnesium compound grains, an area ratio of the Si-rich metallic phase is in a range of 2.5% or more and 10% or less, and a number density of the Si-rich metallic phase having an area of 1 μmor more is in a range of 1,800/mmor more and 14,000/mmor less.
