A sealed battery with a current breaking mechanism, and a conductor member that is, inside the battery, electrically connected to the current breaking mechanism, and that is, outside the battery, electrically connected to the positive electrode external terminal. The current breaking mechanism includes a thin plate-like inversion plate in which an outer peripheral portion thereof is connected to the positive electrode collector member, and an inner peripheral portion thereof is connected to the conductor member. The inversion plate is, upon an increase in pressure inside the battery, capable of having the inner peripheral portion become displaced so as to be separated from the conductor member. An accommodating recess that receives the inner peripheral portion of the inverted collector member separated and displaced from the conductor member is formed in the positive electrode collector member and in a thickness direction of the positive electrode collector member.
