In such a button-type alkaline battery, the negative electrode part, which is formed by weighing and dropping a negative electrode containing powdered zinc as the active material onto a negative terminal plate, is connected to manganese dioxide through a separator made of cellophane or the like. It is common to have a structure in which the active material is made of silver oxide or the like, and the electrode is opposed to a positive electrode mixture that is molded into a predetermined shape and then housed in a positive electrode can.

業性の悪化を＋ｎ ＜という不都合もでてくる。<Problems to be solved by the invention> In recent years, button-type alkaline batteries have tended to become thinner and thinner;
The following problems arise when the following ultra-thin alkaline batteries are made. First, as the filling volume of the negative electrode in the battery decreases in proportion to the thinning of the battery, the number of powdered zinc particles to be weighed becomes significantly smaller, and the powdered zinc weighing mfi'J
The condition becomes extremely worse. For this reason, large variations occur in the amount of powdered zinc filled in the negative electrode, making it difficult to achieve uniform cell performance and ultra-thin design. Furthermore, as the thickness is reduced, the distance between the upper surface of the negative electrode and the upper end of the negative electrode terminal plate becomes less secure, so that zinc powder tends to spill onto the outside of the negative electrode terminal plate. For this reason, be very careful when dropping powdered zinc onto the negative terminal plate, or when applying external vibrations to flatten the powdered zinc that has formed into beads on the negative terminal plate after falling. This not only makes the handling complicated, but also increases the working time, resulting in the inconvenience of deterioration of workability.

The gist is that the negative electrode portion is formed by removing the negative electrode portion. Furthermore, a structure may be adopted in which the battery suspension of the negative electrode is increased by welding a zinc plate to the central part of the zinc layer.
