A negative electrode (6) of an alkaline battery is a wound porous sheet containing zinc, and includes a hollow part (6a). A main body (21) of a negative electrode current collector (20) is disposed in the hollow part (6a). A retainer (22) of the negative electrode current collector (20) is disposed between portions of the negative electrode (6) which are adjacent to each other in the radial direction of the negative electrode (6). The retainer (22) is connected to the main body (21) outside the negative electrode (6). The main body (21) and the retainer (22) of the negative electrode current collector (20) sandwich a portion of the negative electrode (6) which is present between the main body (21) and the retainer (22).
