とができる。The battery pack 1 configured as described above is often mounted on a small boat or the like, and is likely to be splashed by seawater or the like. As described above, when the scattered seawater or the like adheres to the lid 2, a liquid junction is likely to occur in the conventional configuration. According to the above configuration, even when splashing of seawater or the like occurs, the lid 2 and the liquid junction preventing convex portion 6 and the liquid junction preventing concave portion 7 formed between the lids 2 and 2 form the seawater and the like as poles. Since a path that electrically shorts the terminals 3 and 4 is cut off, a liquid junction can be prevented, and damage such as ignition due to the liquid junction can be prevented.
