To provide a thermoelectric element that prevents mutual diffusion of elements between a thermoelectric material and an electrode material when metal-joined with the electrode material.
Thermoelectric elements 2, 3 are each prepared with diffusion preventive layers 9 made of Ni-Ti alloy at junction parts of a thermoelectric material 8 made of an alloy containing Sb, with electrodes 4. The thermoelectric materials 8 are each made of a discharge plasma sintered body of a powder of an alloy having a skutterudite type crystal structure. The diffusion preventive layers 9 are each formed of a discharge plasma sintered body of a powder of an alloy which contains 28 to 83 wt.% Ni and 17 to 72 wt.% Ti, the total amount of Ni and Ti being 100 wt.%.
