An exemplary thermoelectric generator disclosed herein includes: a first electrode and a second electrode opposing each other; and a stacked body having a first end face and a second end face. The stacked body is structured so that first layers made of a first material and second layers made of a second material are alternately stacked, the first material containing a metal and particles having a lower thermal conductivity than that of the metal, the particles being dispersed in the metal, and the second material having a higher Seebeck coefficient and a lower thermal conductivity than those of the first material. Planes of stacking between the first layers and the second layers are inclined with respect to a direction in which the first electrode and the second electrode oppose each other.
