Claims

[Scope of utility model registration request]

(1) A cylindrical metal can filled with a power generation element, a metal sealing plate that closes the opening of the metal can via an insulating gasket, and one pole of the power generation element electrically connected to the metal sealing plate. In an alkaline battery having a current collector embedded in the metal sealing plate, the sealing plate has a convex portion projecting inward, and the convex portion is provided on the head of the current collector where the current collector contacts the inner surface of the metal sealing plate. What is claimed is: 1. An alkaline battery comprising a recess that fits into the recess, and the projection and the recess fit and are electrically connected.

(2) The alkaline electrolyte according to claim 1, wherein the convex portion of the metal sealing plate and the four parts of the current collector head have a cross-section of a ■-shape. (3) The metal sealant The alkaline battery according to claim 1, wherein the convex portion of the plate and the concave portion of the current collector head have a U-shaped cross section.
