摘要：A groove is formed in a ring shape and a ring-shaped convexity is formed on theperiphery of a through-hole of a positive electrode terminal plate. An upper end side of acrimping 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 formedby irradiation with high-energy beams between a distal end side of the crimping part andthe convexity. The mechanical and electrical connection of an exterior terminal and aterminal plate to the crimping part through welding with high-energy beams makes itpossible to provide a prismatic secondary battery of enhanced reliability in which crackingis less likely to occur in the welded spots, the coupling strength between the exteriorterminal and the terminal plate is increased, and fluctuations in the internal resistance arecurbed.
