SHORT-CIRCUIT PREVENTING STRUCTURE OF SEALED BATTERY

PROBLEM TO BE SOLVED: To provide the short preventing structure of a sealed battery, capable of surely preventing the contact of an electrode tab with a battery can, and preventing the short circuit of the sealed battery. SOLUTION: In a sealed battery 10, in which a positive terminal 1 seals the opening part of a battery can 3 via a gasket 2, the positive terminal 1 and a power generating element 5 housed in the battery can 3 are electrically connected via an electrode tab 4, and an insulating plate 6 is placed on the surface on the positive terminal side of the power generating element 5, a projection 7 for obstructing the contact of the electrode tab 4 and the inner surface of the battery can 3 is formed in the insulating plate 6.
