Abstract

The present disclosure provides a technique for constructing an electrode terminal with superior conductivity. An electrode terminal disclosed herein includes: a first member which has a connecting portion that is exposed to outside of the case; and a second member which is a plate-shaped conductive member arranged outside of the case. In addition, the connecting portion penetrates the case and the second member and forms a cap portion having a flat plate shape outside of the second member. Furthermore, a plurality of recessed portions are formed on an upper surface of the cap portion, and a bonding portion due to an intermetallic bond is formed on a boundary, which is between the first member and the second member, below each of the recessed portions. Accordingly, a contact resistance between the first member and the second member can be reduced and conductivity of the electrode terminal can be improved.
