周知のことである。Conventional technology and its problems In recent years, the current consumption of small portable electronic devices has become extremely small, and the memory backup function has become more diverse due to the diversification of memory. There is a growing need to improve the reliability of power sources. In response to this trend, alkaline batteries are required to have a service life of 5 to 10 years, and as a result, it is becoming essential to improve leakage resistance. Improving leakage resistance is nothing but improving sealing technology, and in alkaline batteries, crimp seals are used to squeeze the positive and negative electrode containers together by placing lyamide-based synthetic resin in the sealing part. Since this method is common, the sealing part may become incomplete due to springback. For this reason, attempts have been made to improve leakage resistance by coating the gasket with adhesive, but it is well known that leakage in alkaline batteries proceeds through the following two electrochemical reactions called electrocapillarity. be.

あった。For this reason, Japanese Patent Laid-Open No. 59-65659 discloses that an indium-tin alloy is thermally sprayed on the side surface of the gasket to improve leakage resistance. However, with this method, the gasket deteriorates due to heat during thermal spraying of the alloy, and cannot withstand storage for 5 to 10 years as described above.
