Movable body equipped with battery

A movable body comprising

• a battery including:
• a battery element;
• an outer packaging body configured to accommodate the battery element;
• an electrolytic solution enclosed inside the outer packaging body;
• a positive electrode terminal and a negative electrode terminal, each including a part provided outside the outer packaging body and a part provided inside the outer packaging body, and electrically connected to the battery element;
• and
• a current cut-off device placed inside the outer packaging body, the current cut-off device being provided only with one of the positive electrode terminal and the negative electrode terminal so as to form an electric current path between the battery element and the one of the positive electrode terminal and the negative electrode terminal, the current cut-off device being configured to cut off the electric current path when a pressure in the outer packaging body increases, wherein
• the battery is provided in the movable body as a power source for the movable body such that the one of the positive electrode terminal and the negative electrode terminal that is provided with the current cut-off device, is placed on a vertically upper side relative to the other one of the positive electrode terminal and the negative electrode terminal, the current cut-off device is placed on the vertically upper side relative to a liquid level of the electrolytic solution, and the part of the other one of the positive electrode terminal and the negative electrode terminal that is provided inside the outer packaging body is completely immersed in the electrolytic solution.
