Abstract: To increase thermoelectromotive voltage of a thermoelectric conversion element with a magnetization direction, a temperature gradient direction, and an electromotive force direction orthogonal to each other. A thermoelectric conversion element 1 is formed by annularly winding a thermoelectric material which is radially magnetized and circumferentially generates an electromotive force in accordance with a temperature gradient in the axial direction thereof. Thus, the thermoelectric material is wound not linearly but annularly, so that a connection line for connecting a plurality of thermoelectric materials is not necessary. In particular, when the thermoelectric material is wound in a plurality of turns, the length per unit area of the thermoelectric material in the direction of the electromotive force can be significantly increased, making it possible to significantly increase thermoelectromotive voltage while suppressing increase in the size of the element.
