Description of the Related Art Conventionally, an insulative member is interposed between a positive electrode terminal and a negative electrode terminal of a battery, which are exposed in the same direction. The phenomenon was prevented. Especially in the case of high-power batteries such as lithium batteries and alkaline batteries, when a short circuit occurs, a large current flows, and the batteries themselves generate heat and deform the battery sealing part, or the built-in electrolyte leaks and damages the equipment used. Or let it. Alternatively, when water or the like is interposed between the two terminals and a liquid junction occurs, in a battery having a high potential such as a lithium battery, the electrolysis of water occurs and causes a problem such as corrosion of the terminal metal. there were. Bituminous materials such as epoxy, acrylic, silicon-based polymer materials, pitch, and asphalt, which are excellent in adhesion and adhesion to metal, have been used as insulating members to solve these problems.
