Abstract: The positive electrode substrate exposed portions or the negative electrode substrate exposed portions, or both, of an electrode assembly is split into two groups, and therebetween is disposed an intermediate member made of a resin material and holding one or more connecting conductive members. Collector members for the substrate exposed portions split into two groups is electrically joined by a resistance welding method to the substrate exposed portions split into two groups, together with the connecting conductive member(s) of the intermediate member. The resin material portion of the intermediate member protrudes, in the extension direction of the substrate exposed portions split into two groups, beyond the ends of the substrate exposed portions split into two groups and the ends of the collector member to a prismatic outer can. This structure enables enhanced resistance between the substrate exposed portions and the collector member and curbs variation in the welding strength.

Abstract: A prismatic nonaqueous electrolyte secondary battery includes a convex portion on a stepped portion of a stepped through hole of a positive electrode external conduction member. An upper end side of a caulked portion of a positive electrode terminal member is caulked by being inserted from a side of a small-diameter portion into the stepped through hole of a positive electrode external conduction member, and a convex portion of the positive electrode external conduction member is covered with a tip side of the caulked portion. Therefore, a terminal member and an external conduction member have a great bond strength, and rarely rotate with respect to each other. Thus, there is less concern that a conductivity decreases even when the battery is used under an environment including a lot of vibrations.

Abstract: A groove is formed in a ring shape and a ring-shaped convexity is formed on the periphery of a through-hole of a positive electrode terminal plate. An upper end side of a crimping part of a positive electrode exterior terminal is inserted through the through-hole of the positive electrode terminal plate and crimped, and welded spots are formed by irradiation with high-energy beams between a distal end side of the crimping part and the convexity. The mechanical and electrical connection of an exterior terminal and a terminal plate to the crimping part through welding with high-energy beams makes it possible to provide a prismatic secondary battery of enhanced reliability in which cracking is less likely to occur in the welded spots, the coupling strength between the exterior terminal and the terminal plate is increased, and fluctuations in the internal resistance are curbed.
