    摘要： A thermoelectric conversion material (10) according to an embodiment includes a plurality of parent-phase particles (22) and nanoparticles (30). The parent-phase particles (22) have a crystalline structure. Each of the nanoparticles (30) includes an oxide and exists at an interface between the parent-phase particles (22). The nanoparticles (30) include at least one element that constitutes the crystalline structure. When a range of 6 µm×4 µm of the thermoelectric conversion material (10) is observed with a scanning electron microscope to acquire one sheet of cross-sectional observation image, an average particle diameter d, which is an average of an equivalent circle diameter of a particle group including the parent-phase particles (22) and the nanoparticles (30) which are observed on the cross-sectional observation image, is equal to or more than 100 nm and equal to or less than 1000 nm.
