摘要： Disclosed is a battery 10 including: an electrode group including a positive electrode, a negative electrode, and a separator; an electrolyte; and a battery container accommodating the electrode group and the electrolyte. The battery container includes an accommodating portion 16 having an opening, and a lid sealing the opening of the accommodating portion 16. The battery container includes a liquid-retaining portion 16a retaining the electrolyte therein below the liquid surface of the electrolyte, and a gas-retaining portion 16b retaining gas therein above the liquid surface of the electrolyte. The liquid-retaining portion 16a of the side portion of the battery container is thinner than the gas-retaining portion 16b of the battery container. This suppresses scattering of fragments etc. in the event of rupture of a secondary battery due to an increase in the internal pressure. The safety of the secondary battery is thus increased.
