<P>PROBLEM TO BE SOLVED: To provide a battery case in a nickel metal-hydride battery and its manufacturing method, wherein leakage of hydrogen molecule and steam outside from the wall of the battery case causing deterioration of battery performance are prevented, and wherein a long life-time and the free maintenance over a long term are possible. <P>SOLUTION: In the resin-made battery case for the nickel metal-hydride battery, via a resin layer 31 playing a role as a binder, a metal thin layer 32 consisting of a metallic foil or vapor-deposited metal layer playing a role as a gas barrier to prevent the leakage of the hydrogen molecule and the steam is integrally formed at least on the outer face of a part of the case side part, and furthermore, a resin layer 33 to play a role of protecting the metal thin layer 32 from corrosion is formed on this. <P>COPYRIGHT: (C)2004,JPO |
