PURPOSE: A spring assembly and a test socket using the same are provided to improve electricity transfer characteristic. CONSTITUTION: A first spring(110) has elasticity and conductivity. The first spring is spirally wound in a specific direction. A second spring(120) has the elasticity and the conductivity. The second spring is spirally wound in the opposite direction to the specific direction. The second spring has smaller outer diameter than the inner diameter of the first spring to be inserted into the first spring.
