Thermoelectric element, thermoelectric module and manufacturing method thereof

A thermoelectric module, comprising:

• a first thermoelectric element(s) having one thermoelectric property of P or N type, the first thermoelectric element(s) including a shank at which is located a screw thread, and the screw thread functioning as a radiating fin;
• a second thermoelectric element(s) having another thermoelectric property of P or N type, the second thermoelectric element(s) being formed by precision casting using an evaporative pattern;
• and
• a first connection electrode member(s) to which one end of each of the first and second thermoelectric elements are fastened together, using the screw thread, for electrically connecting therebetween.
