Abstract
A plate-shaped thermoelectric conversion material having a first main surface and a second main surface on the opposite side of the first main surface is formed of semiconductor grains that are in contact with one another. The semiconductor grains each include a particle composed of a semiconductor containing an amorphous phase, and an oxidized layer covering the particle. The distance between the first main surface and the second main surface exceeds 0.5 mm.
