摘要： Provided is a secondary battery which is capable of more reliably cutting off current by increasing a deformation amount of a member, which is deformed by a rise of an internal pressure of a battery container and cuts off current. The secondary battery is provided with a current cut-off mechanism in a current path between an external terminal and an electrode inside a battery container. The current cut-off mechanism is accommodated in the battery container, and is provided with a diaphragm connected to the external terminal and a current collector connected to the electrode. The diaphragm is disposed on an outer side of the battery container than the current collector and has a convex shape toward an inside of the battery container. The current collector includes a concave portion on a surface facing the outer side of the battery container, and the diaphragm is bonded to the concave portion.

摘要： A secondary battery includes a diaphragm which is disposed on a current path between a current collector plate connected to a wound electrode group in a battery container and an external terminal, deforms when an internal pressure of the battery container increases, and breaks the current path. The diaphragm has a convex portion which protrudes to the current collector plate. The current collector plate has a through-hole into which the convex portion is inserted. An inner wall portion of the through-hole and a side wall portion of the convex portion facing each other are welded.
