摘要：Disclosed is a prismatic secondary battery in which a second insulating memberthat has a through-hole is disposed between an inversion plate and a first region of a
positive electrode collector, and through the through-hole the first region of the positiveelectrode collector is electrically connected to the inversion plate by a connectingportion. The positive electrode collector has an annular notch portion that encircles theconnecting portions connecting with the inversion plate. The product of the thickness t ofthe thinnest part of the notch portion and the length L of the notch portion is 0.28 to0.57 mm. There is thus provided a high-reliability prismatic secondary battery including,between the collector and the external terminals, a current interruption mechanism thatis unlikely to be damaged even if high current flows in the battery.
