PROBLEM TO BE SOLVED: To provide an alkaline battery in which the number of welding is reduced and improvement is made for the steady operation of welding of the current collector terminal having a slit. SOLUTION: This is an alkaline battery having a group of electrode plates which are wound via a separator in such a way that the belt shaped positive electrode plate and negative electrode plate with part of electrode plate core exposed at its top end or bottom end protrude upward the exposed portion of the long side portion of one of the electrode plate and protrude downward the exposed portion of the long side portion of the other electrode plate, and the current collector terminals are spot welded to the protruding portions of this electrode plate group. The shape of the electrode tip used for this spot welding is rectangular and the long side L and the width W of the electrode tip are specified and the long side of the electrode tip is disposed and welded to the radius direction of the battery.
