摘要：Problem to be solved: to provide a cylindrical cell having a current cut-offmechanism in which fluctuation in the working pressure is reduced. The cylindrical cellaccording to one aspect of the present invention includes an electrode body having apositive electrode plate and a negative electrode wound around a separator, anelectrolyte, a bottomed cylindrical outer casing housing an electrode body and anelectrolyte, and a sealing body having a current blocking mechanism, and the currentcutoff mechanism is associated with a pressure rise inside the battery The metal plate is
made of a deformable valve body, a metal plate, and an insulating member, the metalplate is electrically connected to one of the positive plate and the negative plate, and thevalve body is joined to the metal plate through an insulating member, and the insulatingmember is valve body andThis is characterized by being held in a compressed statebetween the metal plates.
