Thermoelectric element, thermoelectric module and manufacturing method thereof

It is desirable to save labor and time for positioning and connecting between a thermoelectric element and an electrode in manufacturing a thermoelectric module therefrom. The thermoelectric element is formed with a thread portion on at least one end in an electromotive force generating direction. 期望节省在由热电元件和电极制造热电模块时用于热电元件与电极之间的定位和连接的劳动和时间。热电元件在沿电动势产生方向的至少个端部上形成有螺纹部。
