THE METHOD OF BONDING A THERMOELECTRIC BODY TO A CONDUCTIVE BODY TO PROVIDE LOW RESISTANCE ELECTRICAL CONTACTS BETWEEN SAID BODIES COMPRISING THE STEPS OF DISPOSING A BARRIER LAYER AND CONDUCTIVE GRANULES BETWEEN FACING SURFACE OF THE BODIES TO BE JOINED, AND CONTACTING SAID SURFACES WHILE APPLYING PRESSURE THERETO TO BOND SAID BODIES AND PENETRATE SAID BARRIER LAYR BY SAID CONDUCTIVE GRANULES, THEREBY FORMING LOW-RESISTANCE CONDUCTIVE PATHS BETWEEN SAID BODIES THROUGH SAID BARRIER LAYER.
