PURPOSE: A probe for testing a secondary battery is provided to improve a contact error between the probe and an electrode terminal due to a trouble of a tray by using a battery induction member to guide a position of the secondary battery in a test process. CONSTITUTION: A probe for testing a secondary battery includes an external plunger(120), an internal plunger(110), the first contact part(130), the second contact part(140), and a battery induction member(150). The external plunger(120) has a cylindrical shape. The internal plunger(110) is installed in the inside of the external plunger. The internal plunger is moved by the elastic force. The first contact part(130) is fixed to a bottom part of the internal plunger. The second contact part(140) is fixed to an outer circumference of a bottom part of the external plunger. The battery induction member(150) is used for covering the first and the second contact parts.
