子の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an alkaline battery in which a cathode arm electrically connected to a cathode and a metal ring connected to an anode are bonded by fusion of an insulating material containing silicon oxide. The present invention relates to a method for manufacturing an electrode terminal.

で陰極榛に固着させるものである。As shown in FIG. 1, a typical manufacturing method is such that the cathode ridge 2 located on the center side with respect to the glass 3 has almost the same coefficient of thermal expansion as the glass 3, and the metal ring 1 in contact with the outer periphery of the glass 3.
By composing the material with a material having a larger value than the glass, the glass 3 is heated and melted, and then the glass 3 is compressed by the metal ring 1 on the outer periphery and fixed to the cathode shank due to the difference in thermal expansion during cooling. It is something.

、周辺部品の腐蝕等の原因となっていた。The cathode rod 2 is made of an Fe--Ni alloy, the glass 3 is made of potash soda barum glass having a coefficient of thermal expansion similar to this, and the metal ring 1 is made of pure iron, which is generally the best combination. However, the pure iron metal ring is corroded by the alkaline electrolyte, and the electrolyte leaks from the hermetic seal electrode terminal, contaminating the surface of the terminals and parts in electronic equipment, causing poor contact, poor insulation, and surrounding areas. This caused corrosion of parts.

例について図面を参照にして説明する。In order to eliminate the above-mentioned drawbacks, the present invention aims to improve the corrosion resistance against alkaline electrolytes by applying Nj plating to the base of the metal ring in advance and then applying Cu plating thereon. Embodiments of the present invention will be described below with reference to the drawings.

のである。FIG. 2 is a longitudinal cross-sectional view of a metal ring according to the present invention, in which one or two N layers are added to the base for corrosion protection against alkaline electrolytes.
Two to three layers of Cu plating 6 are applied on the Ni plating to improve adhesion to the glass.
本発明によれば、二層のメッキ層が封着時の加熱により
、母材（純鉄）よりもはるかに耐蝕性の優れた合金層７
となり母材全面を覆い、腐蝕を防ぐ（第３図）。According to the present invention, the alloy layer 7 has much better corrosion resistance than the base material (pure iron) because the two plating layers are heated during sealing.
It covers the entire surface of the base material and prevents corrosion (Figure 3).
