[PROBLEMS] To provide a secondary battery capable of easily assembling a battery without deforming parts, reducing internal resistance and obtaining high output, and a method of manufacturing the secondary battery. SOLUTION: A filter 28 which is a first sealing member which is integrally fixed to a positive electrode current collector plate 25 and is arranged at an opening of an outer can 27 via a gasket 33 which is an insulating member. Along with an explosion-proof valve body 30 as an explosion-proof means for discharging internal gas in response to an increase in the internal pressure, the filter 28 is covered with a spacer 31 as a second sealing member fixed to a filter 28 via an O-ring 29 as a sealing means. Seal the opening of the can 27, The elastic joining piece 26b provided on the negative electrode current collector 26 is By joining to the inner bottom surface, the internal resistance is reduced, the output of the battery is increased, and the components can be assembled without deformation. |
