    Abstract: The present disclosure relates to a jig for measuring a 3-electrode voltage. The jig can measure charging and discharging voltages of a secondary battery in an environment similar to that of an actually used secondary battery by minimizing air contact and electrolyte use of a battery cell. In an embodiment, disclosed is a jig for measuring a 3-electrode voltage that comprises a jig body including a receiving part for mounting a secondary battery in which an electrode assembly is accommodated inside a case. The jig also includes a jig door that opens or closes a side of the jig body in which the receiving part is located. The jig further includes a cathode electrode that is mounted to the jig body, with the cathode electrode including a part being electrically connected to a cathode electrode tab protruding from upper portion of the secondary battery mounted in the receiving part, and with a part of the cathode electrode protruding to outside of the jig. An anode electrode is mounted to the jig body, with the cathode electrode being electrically connected to a conductive member electrically connected to the case of the secondary battery, and the cathode electrode having a part protruding to outside of the jig. A reference electrode penetrates a top plate of the jig body, is inserted into an electrolyte in a core of the secondary battery mounted in the receiving part, and protrudes upward from the jig body.
