Disclosed is an elastic electric contact terminal including: an operation unit formed in the shape of a spring by winding a metal strip to have elasticity; and a contact unit integrally formed on an upper end of the operation unit and forming a flat surface such that an upper surface thereof can be vacuum picked up. A diameter of each turn forming the operation unit increases toward a lower portion from an upper portion, so the adjacent turns overlap each other in a vertical direction and a lower end of the operation unit can be reflow-soldered.
