Abstract
A thermoelectric conversion element includes: a thermoelectric conversion layer containing a thiophene polymer, in which a peak intensity of a diffraction angle (2θ) of 7.9° is 5 times or more a peak intensity of a diffraction angle (2θ) of 25.8° in an X-ray diffraction spectrum of the thermoelectric conversion layer.
