Sealed battery and method of manufacturing sealed battery

A sealed battery comprising:

• a case which houses an electrode body;
• and an electrode terminal for electrically connecting the electrode body and an external conductive material with each other, wherein
• the electrode terminal includes:
• a first member which is a conductive member to be connected to the electrode body inside the case and 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, which has a connection region to be connected to the external conductive material, and which connected to the connecting portion of the first member,
• an upper end of the connecting portion of the first member penetrates the case and the second member and forms a cap portion having a flat plate shape outside of the second member, and
• a plurality of recessed portions are formed on an upper surface of the cap portion, and a bonding portion configured due to an intermetallic bond is formed on a boundary, which is between the first member and the second member, below each of the plurality of recessed portions.
