PROBLEM TO BE SOLVED: To provide a technology for improving adhesive strength between a collector terminal and a core body exposed part of an electrode body.SOLUTION: The process of manufacturing a battery includes a step of bonding a core body exposed part 12a of an electrode body 12 and a collector terminal 14 by solid-phase bonding. The collector terminal 14 has a thin wall part 14a whose thickness is thinner than a thickness of a periphery. In a step of the bonding, the thin wall part 14a is bonded to the core body exposed part 12a. A thickness Z of the thin wall part 14a is roughly equal to a thickness Y of the core body exposed part 12a. |
