Abstract
A thermoelectric conversion unit comprising a thermoelectric conversion device 1 having a cleavage plane 2 and electrodes 3 formed on a pair of opposing surfaces of the thermoelectric conversion device 1, the angle subtended by the electrode-forming surfaces 4 of the thermoelectric conversion device 1 and by the cleavage plane 2 being not smaller than 45 degrees, the surface roughness Ra on the electrode-forming surfaces 4 being from 0.1 to 5 .mu.m, and the electrodes 3 having a thickness larger than a maximum surface roughness Rmax of the electrode-forming surfaces 4. The thermoelectric conversion unit features a high adhesion strength between the thermoelectric conversion device 1 and the electrodes 3, and high reliability.
