An object is to provide a battery with good durability, and a vehicle and a battery-mounting device each having such a battery mounted therein. A battery includes a positive electrode terminal member made of aluminum, a negative electrode terminal member made of copper, a positive electrode resin member made of an insulating resin, covering a part of the terminal member in tight contact therewith, and a negative resin member made of an insulating resin, covering a part of the terminal member in tight contact therewith. A positive electrode resin adhesion surface and a negative electrode resin adhesion surface each have been subjected to a surface treatment. A negative electrode sealing length of a shortest path of negative seal paths is longer than a positive electrode sealing length of a shortest path of positive electrode seal paths.
