Abstract: A fabrication method of a thermoelectric conversion element includes forming a first metal layer containing Cu on a first surface of a thermoelectric conversion layer, and forming a first electrode and a first intermediate layer from the first metal layer. The thermoelectric conversion layer is composed of a thermoelectric conversion material containing Mg and at least one kind of element selected from the group consisting of Sb and Bi, the first intermediate layer is provided between the thermoelectric conversion layer and the first electrode, the first intermediate layer is in contact with the thermoelectric conversion layer, the first electrode is in contact with the first intermediate layer, and a composition of the first intermediate layer is different from both a composition of the first electrode and a composition of the thermoelectric conversion layer.
