There are provided a thermoelectric element and a thermoelectric module that are manufacturable at low cost, suffer little from deterioration in thermoelectric characteristics even after a long period of use, and excel in durability. A thermoelectric element of the invention includes a columnar thermoelectric element main body, an insulating layer disposed on a periphery of the thermoelectric element main body, and a metal layer disposed on an end face of the thermoelectric element main body, the metal layer covering an end face of the insulating layer. Accordingly, a reaction with a solder is prevented and high thermoelectric characteristics is maintained even during a long period of use.
