Definitions

  • the dopant doping average in the first region which is a half region of the thermoelectric conversion layer on one electrode side is half the region of the thermoelectric conversion layer on the other electrode side. It is characterized by being larger than the average dopant doping rate in a certain second region. That is, the present invention is characterized in that the average density of the number of dopants in the first region, that is, the number density is larger than the average density of the dopants in the second region, and the amount of dopant in the first region is increased. More than the amount of dopant in the second region.
  • the thermoelectric conversion element 10 includes a first electrode 14 and a second electrode 16 that are laminated at spaced positions on the substrate 12, and further, the first electrode 14 and the second electrode 16.
  • a thermoelectric conversion layer 18 is laminated on the substrate 12 so as to cover the electrode 16.
