Abstract
According to the present disclosure, the thermal deterioration of metal junction parts formed on a contact interface of constitution members of electrode terminals is suppressed. The electrode terminal of the secondary battery disclosed herein includes a first member having a plate-shaped connection part and a plate-shaped second member connected to the connection part of the first member in a surface-contact manner. Then, the technique disclosed herein includes a metal junction part and a heat-insulating part formed on a contact interface between a connection part of the first member and the second member, and the heat-insulating part is formed outward of the metal junction part in a radial direction centered on the metal junction part. Due to this constitution, the heat-insulating part can block great heat even when such a great heat is applied to a region outside the heat-insulating part, and therefore, the heat deterioration of the metal junction part can be suppressed.
