In this alkaline battery, the linking portion of the gasket includes an annular disc (7f) that is uniform in thickness and has a two-step profile with a bent portion (7g) formed at its middle portion as viewed along the radial direction. The alkaline battery has a reduced axial dimension of the sealing portion and thus achieves improved discharge performance while retaining its safety and leakage-proof performance.
