Thermoelectromotive force generating element, method of producing a thermoelectromotive force generating element, and image sensor

Abstract

To provide a thermoelectromotive force generating element capable of generating thermoelectromotive force with high efficiency while maintaining strength even when the element is miniaturized. A thermoelectromotive force generating element 10 includes: a substrate 11; a thermoelectric conversion layer 12 that is stacked on the substate and includes a P-type thermoelectric material 21 and an N-type thermoelectric material 22; a first electrode 13 on a low temperature side connected to one end of the thermoelectric conversion layer; a second electrode 14 on a high temperature side connected to the other end of the thermoelectric conversion layer; and an absorption portion 15 that is stacked in contact with the second electrode and absorbs heat received from outside, the P-type thermoelectric material and the N-type thermoelectric material forming a PN series connection.
