A secondary battery according to the present invention for achieving the above-stated technical problem comprises: an electrode assembly; a first and second electrode lead connected to the electrode assembly; a pouch case which accommodates the electrode assembly and which is sealed to allow the electrode leads to be drawn to the outside; and a reference electrode assembly with one side inserted to the inside of the electrode assembly and the other side drawn to the outside of the pouch case. According to the present invention, properties of the secondary battery can be easily analyzed without additional work through the disassembly of the secondary battery, and properties of each positive and negative electrode of the secondary battery can be analyzed separately. Additionally, according to the present invention, the properties of the secondary battery can be precisely analyzed by removing measurement deviation can occur when a distance from the positive electrode to the reference electrode and a distance from the negative electrode to the reference electrode are different, and a risk of debasement of sealing performance due to the installation of the reference assembly can be reduced or eliminated.
